The Best 4K Aquarium for Relaxation 🐠 Sleep Relax Meditation Music - 2 hours - 4K UHD Screensaver

One of the loveliest scenes is when Connor carries a drunken Mia from the living room and puts her to bed, gently taking off her clothes while Mia, pretending to be asleep, sneaks an occasional peak and is obviously enjoying the moment.

Fish Tank is a strong and unpredictable film because Mia is a strong though flawed character who refuses to allow her miserable circumstances to control her life.

That the film opens the door long enough to provide a breath of fresh air once again tells us that life can be governed by what is possible rather than what is reasonable and Fish Tank, instead of becoming another sordid study of pathology, becomes an exhilarating dance of liberation.

Edward Edwards developed these glass-fronted aquaria in his patent for a "dark-water-chamber slope-back tank", with water slowly circulating to a reservoir beneath.

Germans soon rivaled the British in their interest. In , an anonymous author had two articles published about the saltwater aquaria of the United Kingdom: However, in , Der See im Glase The Lake in a Glass was published, discussing freshwater aquaria, which were much easier to maintain in landlocked areas.

Published in , Henry D. In 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. Around , the first mechanical aquarium air pump was invented, powered by running water, instead of electricity.

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 the water.

Axelrod influenced many more hobbyists to start keeping fish. 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 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 , aquarium keeping is the second-most popular hobby after stamp collecting. 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.

However, glass as a material is brittle and has very little give before fracturing, though generally the sealant fails first.

The very first modern aquarium made of glass was developed in the 19th century by Robert Warrington. These aquariums had the glass panels attached with metal frames and sealed with putty.

Metal-framed aquariums were still available until the mids, when the modern, silicone-sealed style replaced them.

Acrylic aquariums first became available to the public in the s. Laminated glass is sometimes used, which combines the advantages of both glass and acrylic.

Glass aquaria have been 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, 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 a tropical temperature and requires less capacity from an aquarium heater.

Large aquaria might instead use stronger materials such as fiberglass -reinforced plastics. However, this material is not transparent. 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: A popular positioning choice for plywood aquaria 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: 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 the tank itself.

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 a circular, submerged lid. Pseudokreisels are "U" or semicircle shaped, usually without a lid.

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 a lid. There may also be screens about midway down the sides of the tank, or at the top on the sides.

Another popular setup is the biotope aquarium. Some of the most popular biotopes are the freshwater habitats of the Amazon and Rio Negro rivers, the African rift lake environments of Lake Malawi and Lake Tanganyika , and saltwater coral reefs of Australia , the Red Sea , and the Caribbean.

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 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, [51] 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. Relatively large home aquaria resist rapid fluctuations of temperature and pH , allowing for greater system stability.

Unfiltered bowl-shaped aquaria are now widely regarded as unsuitable for most fish. Advanced alternatives are now available.

Chemical filtration should also be considered under some circumstances for optimum water quality. Practical limitations, most notably the weight of water 1 kilogram per litre 8.

Public aquariums and oceanariums designed for exhibition of large species or environments can be dramatically larger than any home aquarium.

A new trend is to have very small aquariums, termed mini aquariums less than litres or 40 gallons or nano aquariums less than 75 litres or 20 gallons.

These can be either freshwater or saltwater, and are intended to display a tiny but self-contained ecosystem. 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 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.

Wave-making devices have also been constructed to provide wave action. 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. Simple metal tank stands are also available. Large volumes of water enable more stability in 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 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 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 the fish are kept healthy. Daily maintenance consists of checking the fish for signs of stress and disease.

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.

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 , is the most basic measure of water conditions. Rarely, higher salt concentrations are maintained in specialized tanks for raising brine organisms.

Saltwater is typically alkaline, while the pH alkalinity or acidicity of fresh water varies more. Hardness measures overall dissolved mineral content; hard or soft water may be preferred.

Hard water is usually alkaline, while soft water is usually neutral to acidic. Home aquarists typically use tap water supplied through their local water supply network to fill their tanks.

Straight tap water cannot be used in localities that pipe chlorinated water. In 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.

Additives 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 the addition of a commercially available mixture of salts and other minerals.

This can be accomplished by additives, such as sodium bicarbonate, to raise pH. In contrast, public aquaria with large water needs often locate themselves near 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: Cold water aquaria are for fish that are better suited to a cooler environment.

More important than the range is consistency; most organisms are not accustomed to sudden changes in temperatures, which can cause shock and lead to disease.

Water movement can also be important in simulating a natural ecosystem. 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.

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 nitrogen cycle or be removed by passing through zeolite.

Nitrogen waste products become toxic to fish and other aquarium inhabitants at high concentrations. When fish are put into an aquarium, waste can quickly reach toxic concentrations in 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.

This process is known in the aquarium hobby as 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. Another type of bacteria genus Nitrospira converts nitrite into nitrate , a less toxic substance.

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.

In addition to bacteria, 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.

What hobbyists call the nitrogen cycle is only a portion of the complete cycle: 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 is most often addressed through two filtration solutions: Activated carbon filters absorb nitrogen compounds and other toxins , while biological filters provide a medium designed to enhance bacterial colonization.

Activated carbon and other substances, such as ammonia absorbing resins, stop working when their pores fill, so these components have to be replaced regularly.

New aquaria often have problems associated with the nitrogen cycle due to insufficient beneficial bacteria. There are three basic approaches to this: In a fishless cycle , small amounts of ammonia are added to an unpopulated tank to feed the bacteria.

During this process, ammonia , nitrite , and nitrate levels are tested to monitor progress. The "silent" cycle is basically nothing more than densely stocking the aquarium with fast-growing aquatic plants and relying on them to consume the nitrogen , allowing the necessary bacterial populations time to develop.

According to anecdotal reports, the plants can consume nitrogenous waste so efficiently that ammonia and nitrite level spikes seen in more traditional cycling methods are greatly reduced or disappear.

This method is usually done with a small starter population of hardier fish which can survive the ammonia and nitrite spikes, whether they are intended to be permanent residents or to be traded out later for the desired occupants.

The largest bacterial populations are found in the filter, where is high water flow and plentiful surface available for their growth, so effective and efficient filtration is vital.

Sometimes, a vigorous cleaning of the filter is enough to seriously disturb the biological balance of an aquarium.

When Connor lends Mia his camera to film her dancing in preparation for an audition, she uses it to spy on Connor and her mom making love.

One of the loveliest scenes is when Connor carries a drunken Mia from the living room and puts her to bed, gently taking off her clothes while Mia, pretending to be asleep, sneaks an occasional peak and is obviously enjoying the moment.

Live, love and give as good as you get. The aquarium principle 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.

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 the Great Exhibition of In , 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.
