118-686: The Manhattan Beach Pier is a pier located in Manhattan Beach, California on the coast of the Pacific Ocean. The pier is 928 feet (283 m) long and located at the end of Manhattan Beach Boulevard . An octagonal Mediterranean-style building sits at the end of the pier and houses the Roundhouse Aquarium . Surfers usually can be seen below the pier. The pier is popular with locals, tourists, photographers, and artists and for fishing. It offers sunsets and vantage points from

236-472: A saltwater aquarium , though he did not use the term. In 1846, Anne Thynne maintained stony corals and seaweed for almost three years, and was credited as the creator of the first balanced marine aquarium in London. English chemist Robert Warington experimented with a 13-gallon container, which contained goldfish, eelgrass , and snails , creating one of the first stable aquaria. The aquarium principle

354-414: A 400-litre (110 US gal; 88 imp gal) tank with many other fish in it represents only a minor change. For this reason, hobbyists often favor larger tanks, as they require less attention. Several nutrient cycles are important in the aquarium. Dissolved oxygen enters the system at the surface water-air interface. Similarly, carbon dioxide escapes the system into the air. The phosphate cycle

472-1166: A challenge to recreate such environments, and most "true" biotopes will only have a few (if not only one) species of fish and invertebrates. Finally, an emerging concept for the home is that of a wall mounted aquarium, some of which are displayed at the Living Art Marine Center . An aquarium can range from a small glass bowl containing less than 1 litre (2.1 US pt) of water to immense public aquaria that house entire ecosystems such as kelp forests . Relatively large home aquaria resist rapid fluctuations of temperature and pH , allowing for greater system stability. Beginner aquarists are advised to consider larger tanks to begin with, as controlling water parameters in smaller tanks can prove difficult. Small, unfiltered bowl-shaped aquaria are now widely regarded as unsuitable for most fish. In order to keep water conditions at suitable levels, aquariums should contain at least two forms of filtration : biological and mechanical. Chemical filtration should also be considered under some circumstances for optimum water quality. Chemical filtration

590-420: A circular, submerged lid. Pseudokreisels are "U" or semicircle shaped, usually without a lid. Stretch kreisels are a "double gyre" kreisel design, where the tank length is at least twice the height. Using two downwelling inlets on both sides of the tank lets gravity create two gyres in the tank. A single downwelling inlet may be used in the middle as well. The top of a stretch kreisel may be open or closed with

708-425: A cooler environment. Temperature consistency is more important than range. Most organisms are not accustomed to sudden changes in temperatures, which can cause shock and lead to disease. Water temperature can be regulated with a thermostat and heater (or cooler). Water movement can also be important in simulating a natural ecosystem. Aquarists may prefer anything from still water up to swift currents , depending on

826-444: A dazzling aquarium is one of the last surefire ways to impress their peers." A kreisel tank ( kreisel being German for " spinning top " or " gyroscope ") is an aquarium shaped like a horizontal cylinder that is designed to hold delicate animals such as jellyfish and newborn seahorses. These aquariums provide slow, circular water flow with a bare minimum of interior hardware to prevent the inhabitants from becoming injured by pumps or

944-540: A five-member City Council. City Council members are elected every four years. The office of the Mayor of Manhattan Beach rotates every nine months among the members of the City Council, so that each City Council member serves one term as Mayor. A City Manager is appointed by the City Council. An elected City Treasurer serves a four-year term. The Beach Cities Health District , provides health and wellness services to

1062-526: A laboratory and pharmacy. The Aviation Corridor is located along Aviation Boulevard (the city's eastern boundary), south of Rosecrans Avenue, and north of Marine Avenue. Aviation High School was located at the intersection of Manhattan Beach Boulevard and Aviation until it closed in the early 1980s. The zone includes several major entertainment and aerospace complexes, including the Manhattan Beach Studios Media Campus and

1180-399: A lid. There may also be screens about midway down the sides of the tank, or at the top on the sides. It is possible to combine these designs; a circular shaped tank is used without a lid or cover, and the surface of the water acts as the continuation of circular flow. Another popular setup is the biotope aquarium. A biotope aquarium is a recreation of a specific natural environment. Some of

1298-514: A mixed-use center. The Metlox site includes a luxury boutique hotel, spa, restaurants, shops and underground parking. North Manhattan Beach business district is located near the intersection of Rosecrans and Highland and has restaurants and shops.

1416-514: A natural water source (such as a river, lake, or ocean) to reduce the level of treatment. Some hobbyists use an algae scrubber to filter the water naturally. Water temperature determines the two most basic aquarium classifications: tropical versus cold water . Most fish and plant species tolerate only a limited temperature range; tropical aquaria, with an average temperature of about 25 °C (77 °F), are much more common. Temperate or coldwater aquaria are for fish that are better suited to

1534-427: A pier completed until 1920. Engineer A.L. Harris developed the concept of the circular end for less exposure and damage to the pilings by the waves. The pier was completed and dedicated on July 5, 1920. It was a cement pier with a rounded end and it was 928 feet (283 m) long. Octagonal house that now holds a lunch restaurant was completed in 1922. In 1928 the pier was extended out 200 feet (61 m) (at no cost to

1652-433: A popular choice for many home and hobbyist aquarists for many years. Once silicone sealant became strong enough to ensure a long-term water-tight seal, it eliminated the need for a structural frame. In addition to lower cost, glass aquaria are more scratch resistant than acrylic. Although the price is one of the main considerations for aquarists when deciding which of these two types of aquaria to purchase, for very large tanks,

1770-528: A population of 35,135. The population density was 8,914.7 inhabitants per square mile (3,442.0/km ). The racial makeup of Manhattan Beach was 29,686 (84.5%) White (79.3% Non-Hispanic White), 290 (0.8%) Black or African American (U.S. Census), 59 (0.2%) Native American , 3,023 (8.6%) Asian , 49 (0.1%) Pacific Islander , 409 (1.2%) from other races , and 1,619 (4.6%) from two or more races. There were 2,440 people of Hispanic or Latino origin, of any race (6.9%). The Census reported that 35,107 people (99.9% of

1888-686: A sandy beach. The McMartin preschool trials , an example of day care sex abuse hysteria , started with investigations of a Manhattan Beach preschool in 1983. The trials ran from 1987 to 1990 and resulted in no convictions. HBO dramatized this case in the Emmy -winning Indictment: The McMartin Trial , which was partially filmed in Manhattan Beach. Manhattan Beach benefits from ocean breezes that provide clean air and summer temperatures that are 10 to 20 °F (5.6 to 11.1 °C) cooler than

2006-535: A score of 926 on the 2010 California Academic Performance Index. Each individual school also ranks at the top of its respective category. Manhattan Beach is currently ranked as one of the best suburbs in Los Angeles Country for its high-earning and well educated residents. Manhattan Beach's top performing school district is currently ranked as the third best in the state of California, behind only Palo Alto and South Pasadena. and Forbes Magazine ranked

2124-465: A small glass bowl, a few liters in volume, to immense public aquaria of thousands of liters. Specialized equipment maintains appropriate water quality and other characteristics suitable for the aquarium's residents. In 1369, the Hongwu Emperor of China established a porcelain company that produced large porcelain tubs for maintaining goldfish ; over time, people produced tubs that approached

2242-401: A tank by diluting effects from death or contamination events that push an aquarium away from equilibrium. The bigger the tank, the easier such a systemic shock is to absorb, because the effects of that event are diluted. For example, the death of the only fish in an 11-litre (3 US gal; 2 imp gal) tank causes dramatic changes in the system, while the death of that same fish in

2360-482: A ten-year period. The beach is approximately 2.1 miles long and 400 feet wide. In the early part of the last century, the beach was narrow (approximately 150 feet) and sloping. From 1938 to 1989, it more than doubled in width when large quantities of sand were placed on beaches to the north during construction of the Hyperion Treatment Plant , Marina del Rey , and Scattergood Power Plant. The sand

2478-449: A tropical temperature and requires less capacity from an aquarium heater. Acrylic-soluble cements are used to directly fuse acrylic together. Acrylic allows for the formation of unusual shapes, such as the hexagonal tank. Acrylics are easier to scratch than glass, but unlike glass, scratches in acrylic can be polished out. Large aquaria might instead use stronger materials such as fiberglass -reinforced plastics . However, this material

2596-405: A youth swim team and adult swim club. Bruce's Beach (formerly Culiacan Park) is north of downtown. For over 50 years, the city of Manhattan Beach hosts an annual Hometown Fair at Live Oak Park in downtown Manhattan Beach. Popular among community residents, the fair features food and drink, live music, games and booths to raise funds for local causes. The city of Manhattan Beach is governed by

2714-614: Is 244 feet high, and it is located in the city's southwest region. The only remaining exposed sand dune is at Sand Dune Park , where sand resembling the original landscape can also be found. In the late 1920s, excess sand from Manhattan Beach was purchased by Hawaiʻian developers, who negotiated a deal with the Kuhn Brothers Construction Company to ship the sand across the Pacific Ocean from Manhattan Beach via Los Angeles Harbor to Waikiki Beach over

2832-431: Is an important, although often overlooked, nutrient cycle. Sulfur, iron, and micronutrients also cycle through the system, entering as food and exiting as waste. Appropriate handling of the nitrogen cycle , along with supplying an adequately balanced food supply and considered biological loading, is enough to keep these other nutrient cycles in approximate equilibrium. An aquarium must be maintained regularly to ensure that

2950-555: Is considered the first surf shop. The Catalina Classic Paddleboard Race to Catalina Island begins here. A sculpture of Duke Kahanamoku flanked by a male knee paddler and a female prone paddler commemorating the race was installed in 2023. Manhattan Beach, California Manhattan Beach is a city in southwestern Los Angeles County, California , United States, on the Pacific coast south of El Segundo , west of Hawthorne and Redondo Beach , and north of Hermosa Beach . As of

3068-501: Is considered the heart of the city. The area runs along Manhattan Beach Boulevard and the streets perpendicular to the Manhattan Beach Pier and Valley Drive. There are Zagat-rated casual fine-dining restaurants, specialty boutiques and retailers that create a pedestrian-friendly, mixed-use downtown center. The Metlox site, where the pottery factory once stood for decades, was closed in the early 1990s and redeveloped into

3186-436: Is frequently achieved via activated carbon , to filter medications, tannins , and/or other known impurities from the water. Reef aquaria under 100 litres (26 US gal; 22 imp gal) have a special place in the aquarium hobby; these aquaria, termed nano reefs (when used in reefkeeping), have a small water volume, under 40 litres (11 US gal; 9 imp gal). Practical limitations, most notably

3304-614: Is keeping them in a wall. Here the use of plywood is hidden by sinking the aquarium inside the wall. Putting insulation between the two helps with the insulation of a heated tank. Objects used for aquariums include: coffee tables, sinks, and even toilets. Another such example is the MacQuarium , an aquarium made from the shell of an Apple Macintosh computer . In recent years, elaborate custom-designed home aquariums costing hundreds of thousands of dollars have become status symbols—according to The New York Times , "among people of means,

The Aquarium includes a shark tank, tide pool touch tank with animals common to Southern California , tanks with lobsters , and baby sharks as well as brightly colored, non-native fish and invertebrates . During the summer, the aquarium is open from 2PM to 5PM on weekdays and 10AM to sunset on weekends. During the rest of the year, it

3540-471: Is not transparent. Reinforced concrete is used for aquaria where weight and space are not factors. Concrete must be coated with a waterproof layer to prevent the water from breaking down the concrete, as well as preventing contamination of the water by the concrete. Plywood can also be used when building aquaria. The benefits of using plywood include: lower construction costs, less weight, and better insulation. A popular positioning choice for plywood aquaria

3658-536: Is now focused on real estate development and opened AdventurePlex, a Manhattan Beach fitness center for kids and their families, in 2002. Filled with mazes , tunnels, outdoor rock climbing walls, complex ropes courses , and an indoor gym , AdventurePlex challenges children physically and intellectually in health-focused recreational activities .

3776-478: Is only a portion of the complete cycle: nitrogen must be added to the system (usually through food provided to the tank inhabitants), and nitrates accumulate in the water at the end of the process, or become bound in the biomass of plants. The aquarium keeper must remove water once nitrate concentrations grow, or remove plants which have grown from the nitrates. Hobbyist aquaria often do not have sufficient bacteria populations to adequately denitrify waste. This problem

3894-482: Is open from 2 p.m. to 8 p.m. on weekdays and 9 a.m. to 8 p.m. on weekends. In January 2018, the aquarium was closed and construction began on a major renovation project. The sealife was relocated to a temporary structure near the entrance to the pier during the renovations. The aquarium reopened on November 5, 2018 with an all-new interior. The octagonal building includes a Spanish tile roof and large gooseneck reflectors to improve lighting. According to Pierfishing.com

( Nitrobacter bacteria were previously believed to fill this role. While biologically they could theoretically fill the same niche as Nitrospira , it has recently been found that Nitrobacter are not present in detectable levels in established aquaria, while Nitrospira are plentiful.) However, commercial products sold as kits to "jump start"

5546-826: The Great Exhibition of 1851. In 1853, the aquarium craze was launched in England by Philip Henry Gosse who created and stocked the first public aquarium in the London Zoo which came to be known as the Fish House. Gosse coined the word "aquarium", opting for this term (instead of "aquatic vivarium" or "aqua-vivarium") in 1854 in his book The Aquariums: An Unveiling of the Wonders of the Deep Water . In this book, Gosse primarily discussed saltwater aquaria. In

6136-554: The Victorian era in the United Kingdom, a common design for the home aquarium was a glass front with the other sides made of wood (made watertight with a pitch coating). The bottom would be made of slate and heated from below. More advanced systems soon began to be introduced, along with tanks of glass in metal frames. During the latter half of the 19th century, a variety of aquarium designs were explored, such as hanging

6254-611: The aquascaping designs of Takashi Amano influencing fishkeepers to treat home aquariums as aesthetically pleasing compositions, rather than simply as a way of displaying fish specimens. In the United States, as of 1996, aquarium keeping is the second-most popular hobby after stamp collecting . In 1999, an estimated 9.6 million US households owned an aquarium. Figures from the 2005/2006 APPMA National Pet Owners Survey report that Americans own approximately 139 million freshwater fish and 9.6 million saltwater fish. Estimates of

6372-447: The gravel , or other substrate if the aquarium has one; however some manage to avoid this entirely by keeping it somewhat self-sufficient. A good habit is to remove the water being replaced by "vacuuming" the gravel with suitable implements, as this will eliminate uneaten foods and other residues that settle on the substrate . In many areas tap water is not considered to be safe for fish to live in because it contains chemicals that harm

6490-481: The nitrogen cycle or be removed by passing through zeolite . Ammonia is also produced through the decomposition of plant and animal matter, including fecal matter and other detritus . Nitrogen waste products become toxic to fish and other aquarium inhabitants at high concentrations. In the wild, the vast amount of water surrounding the fish dilutes ammonia and other waste materials. When fish are put into an aquarium, waste can quickly reach toxic concentrations in

Part of the wave motor may still be buried in the sands at the shore end of the present pier. This "old iron pier", as it was called, was destroyed by a major storm in 1913. Lack of money, lawsuits, storms, World War I and debates about when and where to build another pier delayed Manhattan Beach from having

6726-661: The weight of water (1 kilogram per litre (8.345 lb/U.S. gal; 10.022 lb/imp gal)) and internal water pressure (requiring thick glass siding) of a large aquarium, restrict most home aquaria to a maximum of around 1 cubic metre in volume (1000 L, weighing 1,000 kg or 2,200 lb ). Some aquarists, however, have constructed aquaria of many thousands of litres. Public aquariums and oceanariums designed for exhibition of large species or environments can be dramatically larger than any home aquarium. The Georgia Aquarium , for example, features an individual aquarium of 6,300,000 US gallons (24,000,000 L). A new trend

6844-429: The 1850s, the aquarium became a fad in the United Kingdom. Tank designs and techniques for maintaining water quality were developed by Warington, later cooperating with Gosse until his critical review of the tank water composition. Edward Edwards developed these glass-fronted aquaria in his 1858 patent for a "dark-water-chamber slope-back tank", with water slowly circulating to a reservoir beneath. Germans soon rivaled

6962-520: The 1960s, metal frames made marine aquaria almost impossible due to corrosion, but the development of tar and silicone sealant allowed the first all-glass aquaria made by Martin Horowitz in Los Angeles, CA. The frames remained, however, though purely for aesthetic reasons. Japan played an increasingly important role in shaping aquarium design in the latter part of the twentieth century, with

Polliwog Park is the largest and most popular park. Located on Manhattan Beach Boulevard, two blocks west of Aviation Boulevard, Polliwog Park includes

7670-482: The addition of a commercially available mixture of salts and other minerals. Some aquarists modify water's alkalinity, hardness, or dissolved content of organics and gases, before adding it to their aquaria. This can be accomplished by additives, such as sodium bicarbonate, to raise pH. Some aquarists filter or purify their water through deionization or reverse osmosis prior to using it. In contrast, public aquaria with large water needs often locate themselves near

7788-548: The aquarium on a wall, mounting it as part of a window , or even combining it with a birdcage . Around 1908, the first mechanical aquarium air pump was invented, powered by running water, instead of electricity. The introduction of the air pump into the hobby is considered by several historians of the hobby to be a pivotal moment in its development. Aquaria became more widely popular as houses had an electricity supply after World War I . Electricity allowed artificial lighting, as well as aeration , filtration , and heating of

7906-505: The aquarium's inhabitants. Many aquaria incorporate a hood, containing the lights, to decrease evaporation and prevent fish from leaving the aquarium (and anything else from entering the aquarium). Combined biological and mechanical aquarium filtration systems are common. These either convert ammonia to nitrate (removing nitrogen at the expense of aquatic plants), or to sometimes remove phosphate . Filter media can house microbes that mediate nitrification . Filtration systems are sometimes

8024-491: The aquarium's inhabitants. Water movement can be controlled via aeration from air pumps, powerheads, and careful design of internal water flow (such as location of filtration system points of inflow and outflow). Of primary concern to the aquarist is management of the waste produced by an aquarium's inhabitants. Fish, invertebrates, fungi , and some bacteria excrete nitrogen waste in the form of ammonia (which converts to ammonium , in water) and must then either pass through

The pier was a popular spot for Southern California surfers in the 1940s, the early days of modern surfing. Dale Velzy , the first commercial surfboard shaper , started his business building and repairing boards under the pier before renting a nearby storefront in 1949, starting what

8378-460: The behavior and survival of tank inhabitants. An aquarium can be placed on an aquarium stand. Because of the weight of the aquarium, a stand must be strong as well as level. A tank that is not level may distort, leak, or crack. These are often built with cabinets to allow storage, available in many styles to match room decor . Simple metal tank stands are also available. Most aquaria should be placed on polystyrene to cushion any irregularities on

8496-550: The city of Manhattan Beach to the state. During the next four decades the pier would remain a focus of beachfront activity, but Mother Nature and old age took their toll and by the 1980s the pier was in sad shape and in need of renovation. Restoration took place in the early 1990s with a focus on retention of the old-time appearance, much like Pier 7 in San Francisco . The original pier had to be fixed as old age and decay required extensive repair, and in fact made it unsafe by

8614-453: The city used eminent domain to seize the land from the Black property owners under the pretense of building a park. Bruce's attorney noted that there was a lot of vacant property located on both sides of Bruce's Beach that could have been used for a public park, and that the city's insistence in seizing Bruce's property was a ruse to carry out the city's racist objection to Black people using

8732-568: The city's school district, MBUSD, as the sixth best school district in the United States. Private schools located in Manhattan Beach include American Martyrs Catholic School (of the Roman Catholic Archdiocese of Los Angeles ), Manhattan Academy, Montessori School of Manhattan Beach and Journey of Faith Christian School. Residents of Manhattan Beach were in the Wiseburn School District until 1913, when

8850-529: The city) when a Captain Larsen of Redondo Beach offered to pay for an extension in exchange for the rights to run a shoreboat between the pier and his barge Georgina. On January 9, 1940, 90 feet (27 m) of the extension was ripped away during a winter storm. The extension was never repaired and the remaining section was swept away in February 1941. In 1946 the pier and adjoining beach were deeded over from

8968-529: The craze in England being over, moved to Grindel Dammthor, Hamburg, to supervise the installation of the circulating system and tanks at the Hamburg Aquarium . During the 1870s, some of the first aquarist societies were appearing in Germany. The United States soon followed. Published in 1858, Henry D. Butler's The Family Aquarium was one of the first books written in the United States solely about

9086-421: The enclosed environment unless the tank is cycled to remove waste. A well-balanced tank contains organisms that are able to metabolize the waste products of other aquarium residents, recreating a portion of the nitrogen cycle . Bacteria known as nitrifiers (genus Nitrosomonas ) metabolize nitrogen waste. Nitrifying bacteria capture ammonia from the water and metabolize it to produce nitrite . Nitrite

9204-424: The entire length of the beach and the beach is cleaned and groomed daily by crews from LA County Beaches and Harbors Department. Along the Strand at the eastern edge of the beach is a concrete bike path for bicycles. The bikeway extends north to Santa Monica and south to Torrance. A separate 2.1-mile (3.4 km) pedestrian walkway runs alongside the bike path. Restrooms and shower facilities are provided adjacent to

9322-779: The first public aquarium at the London Zoo in 1853, and published the first manual, The Aquarium: An Unveiling of the Wonders of the Deep Sea in 1854. Small aquariums are kept in the home by hobbyists . There are large public aquariums in many cities. Public aquariums keep fish and other aquatic animals in large tanks. A large aquarium may have otters , dolphins , sharks , penguins , seals , and whales . Many aquarium tanks also have plants. An aquarist owns fish or maintains an aquarium, typically constructed of glass or high-strength acrylic . Aquaria with flat walls are known as fish tanks or simply tanks, while those with rounded walls are known as fish bowls . Size can range from

9440-557: The first person to create aquaria for experimenting with aquatic organisms. This experimentation lead to several discoveries, including the first direct evidence that argonauts , a marine cephalopod, create their own shells. In 1836, soon after his invention of the Wardian case , Dr. Nathaniel Bagshaw Ward proposed to use his tanks for tropical animals. In 1841 he did so, though only with aquatic plants and toy fish. However, he soon housed real animals. In 1838, Félix Dujardin noted owning

9558-416: The fish are kept healthy. Daily maintenance consists of checking the fish for signs of stress and disease . Also, aquarists must make sure that the water has a good quality and it is not cloudy or foamy and the temperature of the water is appropriate for the particular species of fish that live in the aquarium. Typical weekly maintenance includes changing around 10–30% or more of the water while cleaning

9676-594: The fish. Tap water from those areas must be treated with a suitable water conditioner, such as a product which removes chlorine and chloramine and neutralizes any heavy metals present. The water conditions must be checked both in the tank and in the replacement water, to make sure they are suitable for the species. The solute content of water is perhaps the most important aspect of water conditions, as total dissolved solids and other constituents dramatically impact basic water chemistry, and therefore how organisms interact with their environment. Salt content, or salinity ,

9794-473: The glass panels attached with metal frames and sealed with putty. Metal-framed aquariums were still available until the mid-1960s, when the modern, silicone-sealed style replaced them. Acrylic aquariums first became available to the public in the 1970s. Laminated glass is sometimes used, which combines the advantages of both glass and acrylic. Today, most aquaria consist of glass panes bonded together by 100% silicone sealant, with plastic frames attached to

9912-410: The inland regions of Southern California. The city has a total area of 3.9 square miles (10 km ). Manhattan Beach features 2.1 miles (3.4 km) of ocean frontage. A majority of the land in Manhattan Beach was once exposed sand dunes, which now lie beneath the city's buildings and streets. The underlying dunes afford residents ocean views throughout western portions of the city. The tallest hill

10030-517: The late 1980s (when a jogger was injured by falling concrete). The pier was restored to its 1920s appearance and a dedication ceremony was held in 1992. In 1995, the pier was declared a state historic landmark. It is the oldest standing concrete pier on the West Coast. It is managed by the County of Los Angeles, Department of Beaches and Harbors. California Historical Landmark Marker NO. 1018 at

10148-873: The most common ancestries in 2000. Canada and the United Kingdom were the most common foreign places of birth. According to the city's 2010 Comprehensive Annual Financial Report, the top employers in the city are: Residential prices in Manhattan Beach are among the highest in the state of California. In 2013, the Dataquick study reported that more homes exceeding $ 1 million were sold in Manhattan Beach than any other city in California. Pacific Palisades , Beverly Hills , La Jolla , Malibu, Bel-Air, Orinda, Atherton, Montecito, and other high end cities in California ranked behind Manhattan Beach. The Higley 100 Census survey found that The Hill Section of Manhattan Beach

10266-678: The most complex component of home aquaria. Aquarium heaters combine a heating element with a thermostat , allowing the aquarist to regulate water temperature at a level above that of the surrounding air, whereas coolers and chillers (refrigeration devices) are for use anywhere, such as cold water aquaria, where the ambient room temperature is above the desired tank temperature. Thermometers used include glass alcohol thermometers, adhesive external plastic strip thermometers , and battery-powered LCD thermometers. In addition, some aquarists use air pumps attached to airstones or water pumps to increase water circulation and supply adequate gas exchange at

10384-509: The most expensive real estate per square foot in the United States. Since 2010, new property developments in Manhattan Beach cannot exceed two lot parcels. Size and appearance restrictions were enacted by the Manhattan Beach City Council to preserve the appearance of the beachfront community after three lots were joined to create a 16,000-square-foot (1,500 m ) oceanside home in 2008. "Downtown" Manhattan Beach

10502-716: The most popular biotopes are the freshwater habitats of the Amazon River , the Rio Negro River, the African rift lake environments of Lake Malawi and Lake Tanganyika , and saltwater coral reefs of Australia , the Red Sea , and the Caribbean Sea . The fish, plants, substrate, rocks, wood, coral, and any other component of the display should completely match that of the local natural environment. It can be

10620-539: The nitrogen cycle often still contain Nitrobacter . Aquatic plants also eliminate nitrogen waste by metabolizing ammonia and nitrate. When plants metabolize nitrogen compounds, they remove nitrogen from the water by using it to build biomass that decays more slowly than ammonia-driven plankton already dissolved in the water. Some hobbyists also use "anoxic filtration," which relies on bacteria that live in low-oxygen environments. The nitrogen cycle in an aquarium

10738-484: The numbers of fish kept in aquaria in Germany suggest at least 36 million. The hobby has the strongest following in Europe, Asia, and North America. In the United States, 40% of aquarists maintain two or more tanks. Over time, there has been an increasing appreciation of the usefulness of access to an aquarium to provide potential stress reduction and improvement of mood in people observing aquatic life. According to

10856-410: The past, it was possible to "condition" the water by simply letting the water stand for a day or two, which allows the chlorine time to dissipate. However, chloramine is now used more often and does not leave the water as readily. Water conditioners formulated to remove chlorine or chloramine are often all that is needed to make the water ready for aquarium use. Brackish or saltwater aquaria require

10974-643: The pier, yields small tom cod (white croaker) and herring (queenfish), jacksmelt, yellowfin croaker and an occasional halibut. Action at the end of the pier is improved by the surrounding artificial reef which is located about 65 feet (20 m) from the end. Fish at the deepest water end include bonito, Pacific mackerel, jack mackerel, barracuda, an occasional white seabass or even yellowtail, and reef visitors like kelp bass, sand bass and sculpin (scorpionfish). The resident species in Santa Monica Bay may be dangerous to eat, but those that migrate in and out of

11092-639: The population) lived in households, 28 (0.1%) lived in non-institutionalized group quarters, and 0 (0%) were institutionalized. There were 14,038 households, out of which 4,735 (33.7%) had children under the age of 18 living in them, 7,583 (54.0%) were opposite-sex married couples living together, 892 (6.4%) had a female householder with no husband present, 438 (3.1%) had a male householder with no wife present. There were 695 (5.0%) unmarried opposite-sex partnerships , and 85 (0.6%) same-sex married couples or partnerships . 3,627 households (25.8%) were made up of individuals, and 1,078 (7.7%) had someone living alone who

11210-428: The price difference tends to disappear. Acrylic aquaria are now the primary competitor with glass. Prior to the invention of UV stabilization , early acrylic aquaria discolored over time with exposure to light; this is no longer the case. Acrylic is generally stronger than glass, weighs less, and provides a certain amount of temperature insulation. In colder climates or environments, it is easier to achieve and maintain

11328-462: The public beach. In 2021, California Governor Gavin Newsom signed legislation authorizing the transferring of the property to descendants of the family. The land in Manhattan Beach was formerly sand dunes. During the 1920s and 1930s, Kuhn Brothers Construction Company leveled uneven sandy sites and some excess sand was sold and shipped to Waikiki, Hawaii , to convert their reef and rock beach into

11446-532: The research of having an aquarium is many health benefits like reduce stress, blood pressure and heart rate improvement, better quality sleep , reduce anxiety and pain , therapy of excited children, Alzheimer's therapy and improve productivity . The first modern aquarium made of glass was developed in the 19th century by Robert Warrington. During the Victorian age , glass aquariums commonly had slate or steel bottoms, which allowed them to be heated underneath by an open-flame heat source. These aquariums had

11564-412: The residents of Hermosa Beach , Manhattan Beach, and Redondo Beach . It is funded partially by over $ 3 million annually from property taxes. The voters of the three beach cities elect the 5-member Board of Directors to 4-year terms. One of 78 California Health Districts, it was created in 1955 as South Bay Hospital which no longer exists and took on its current name in 1993. Beach Cities Health District

11682-421: The sandy beach area yields the normal surf species; barred surfperch, croakers, small rays and guitarfish (shovelnose shark). The pier is known for barred surfperch fishing. At times, anglers catch hundreds of them within an hour of time, using mainly small jigs and sand crabs. The area around the pilings yields pileperch, walleye surfperch, silver surfperch, and other common pier species. Mid-pier, casting away from

11800-486: The shape of modern fish bowls. Leonhard Baldner , who wrote Vogel-, Fisch- und Tierbuch (Bird, Fish, and Animal Book) in 1666, maintained weather loaches and newts . It is sometimes held that the aquarium was invented by the Romans, who are said to have kept sea barbels in marble-and-glass tanks, but scholars doubt the veracity of this. In 1832, Jeanne Villepreux-Power , a pioneering French marine biologist, became

11918-640: The shore and hillside. The pier includes the Volleyball Walk of Fame, featuring plaques dedicated to past winners of the Manhattan Beach Open beach volleyball tournament. In 1897, the Potencia Company was incorporated to develop land in the area and proposed a seaside resort with wharves and piers. The area was named Potencia, but the city of Manhattan was incorporated in 1912 with the word "Beach" being added in 1927. The name

12036-672: The site reads: NO. 1018 MANHATTAN BEACH STATE PIER - Designed by City Engineer A.L. Harris, this pier was constructed by the City of Manhattan Beach during the years 1917-1920. The roundhouse building was added a year later. Harris' innovative design featured a rounded end to the pier, which helped it withstand the pounding of the Pacific. Although the roundhouse was reconstructed in 1989, the pier itself survives as Southern California's oldest remaining example of early reinforced concrete pier construction. The Roundhouse Marine Studies Lab and Aquarium

12154-399: The tank itself. The tank has no sharp angles around its sides and keeps the housed animals away from plumbing. Water moving into the tank gives a gentle flow that keeps the inhabitants suspended. Water leaves the tank through a screen which prevents animals from being drawn into the pump intake or overflow line. There are several types of kreisel tanks. In a true kreisel, a circular tank has

12272-579: The underlying surface or the bottom of the tank itself that may cause cracks. However, some tanks have an underframe making this unnecessary. Another important consideration for aquariums is their electrical usage. Water is expensive to keep heated, along with the lights that many aquariums, especially those with live plants have. New aquarists should also pay close attention to their electrical setup for their aquarium, taking care to set up power connections with drip loops to prevent water from getting to outlets. Large volumes of water enable more stability in

12390-580: The upper and lower edges for decoration. The glass aquarium is standard for sizes up to about 1,000 litres (260 US gal; 220 imp gal). However, glass is brittle and has very little give before fracturing, though generally the sealant fails first. Aquaria are made in a variety of shapes, such as cuboid , hexagonal , angled to fit in a corner (L-shaped), and bow-front (the front side curves outwards). Fish bowls are generally either made of plastic or glass, and are either spherical or some other round configuration in shape. Glass aquaria have been

12508-400: The water surface. Wave-making devices have also been constructed to provide wave action. An aquarium's physical characteristics form another aspect of aquarium design. Size, lighting conditions, density of floating and rooted plants, placement of bog-wood , creation of caves or overhangs, type of substrate , and other factors (including an aquarium's positioning within a room) can all affect

12626-611: The water. Initially, amateur aquarists kept native fish (with the exception of goldfish); the availability of exotic species from overseas further increased the popularity of the aquarium. Jugs made from a variety of materials were used to import fish from overseas, with a bicycle foot pump for aeration. Plastic shipping bags were introduced in the 1950s, making it easier to ship fish. The eventual availability of air freight allowed fish to be successfully imported from distant regions. Popular publications started by Herbert R. Axelrod influenced many more hobbyists to start keeping fish. In

12744-404: The way to Redondo Beach with a substation constructed in later years at Center Street, which today is Manhattan Beach Boulevard. George H. Peck owned the land that became part of the north section of Manhattan Beach. A coin flip decided the town's name. Around 1902, the beach suburb was named "Manhattan" after developer Stewart Merrill's home, the New York City borough of Manhattan . "Beach"

Live Oak Park in the downtown area has ball fields, batting cages, playground equipment, basketball courts, tennis courts, and picnic tables. Additionally, Begg pool offers comprehensive swimming programs year around for both adults and children including instruction, recreational swimming, water aerobics, and even

13334-591: Was appended to the city's name, in 1927, at the behest of the postmaster. Incorporation of the City of Manhattan Beach won in a vote held on November 26, 1912. Mrs. W. A. Bruce, a landowner of property near the coast, created the first beach resort for Black Americans in Southern California, Bruce's Beach . Bruce set up a small portable cottage with a stand in front where soda and lunches were sold. There were two dressing tents with showers, and fifty bathing suits were available for rent. Peck's land

13452-689: Was carried southward by the ocean's natural littoral flow and widened Manhattan Beach. Every August, the city hosts the Manhattan Beach Open volleyball tournament and the International Surf Festival. The city has several distinct neighborhoods, including the "Strand", "Sand Section", "Hill Section", "Tree Section", "Gas Lamp Section", "Manhattan Village", "Manhattan Heights", "East Manhattan Beach" (Manhattan Village, Manhattan Heights, Liberty Village), "The Poet's Section" (Shelley, Tennyson, Longfellow, Keats), and "El Porto" (North Manhattan Beach). The Roth Tract, between Herrin and Peck,

13570-465: Was chosen by land developer Stewart Merrill . A pier is believed to have been one of the first features built when the Manhattan Beach community was developed. Two wooden piers were built in 1901, one at Center Street (later renamed Manhattan Beach Boulevard) and one at Marine Avenue called Peck's Pier and Pavilion. The Center Street Pier was 900 feet (270 m) long and pylons were made by fastening three railroad rails together and driving them into

13688-505: Was fully developed by Warington, explaining that plants added to water in a container would give off enough oxygen to support animals, so long as their numbers do not grow too large. He published his findings in 1850 in the Chemical Society's journal . The keeping of fish in an aquarium became a popular hobby and spread quickly. In the United Kingdom, it became popular after ornate aquaria in cast-iron frames were featured at

13806-517: Was likely inhabited by the Tongva tribe of Native Americans. Archeological work in the nearby Chowigna excavation show evidence of inhabitants as far back as 7,100 years ago. The Tongva Village of Ongovanga was located near neighboring Redondo Beach . In the mid-18th century, the Portolá expedition was the first European land exploration of present-day California. It traveled north from San Diego to

13924-542: Was located between Bruce's land and the beach itself, and Bruce erected "no trespassing signs" on his land, which required beachgoers to walk a half-mile around his land in order to go to the beach. Many beachgoers did so, which made the nearby white landowners unhappy. In the 1920s, the Ku Klux Klan began violently harassing the resort's visitors, the Bruce family, and four other Black families that bought lots. In 1924,
