Views Read Edit View history. High biological loading siege auto groupe 1 geant casino a more complicated tank ecology, which in turn means that equilibrium is uncharted auf deutsch to upset. There are three basic approaches to this:

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. Therefore, it is recommended to rinse mechanical filters in an outside bucket of aquarium water to dislodge organic materials that contribute to nitrate problems, while preserving bacteria populations.

Another safe practice consists of cleaning only half of the filter media during each service, or using two filters, only one of which is cleaned at a time.

The biological load, or bioload, is a measure of the burden placed on the aquarium ecosystem by its inhabitants. High biological loading presents a more complicated tank ecology, which in turn means that equilibrium is easier to upset.

Several fundamental constraints on biological loading depend on aquarium size. The bacteria population depends on the physical space they have available to colonize.

Physically, only a limited size and number of plants and animals can fit into an aquarium while still providing room for movement. Biologically, biological loading refers to the rate of biological decay in proportion to tank volume.

Adding plants to an aquarium will sometimes help greatly with taking up fish waste as plant nutrients. Although an aquarium can be overloaded with fish, an excess of plants is unlikely to cause harm.

Decaying plant material, such as decaying plant leaves, can add these nutrients back into the aquarium if not promptly removed. Limiting factors include the oxygen availability and filtration processing.

Aquarists have rules of thumb to estimate the number of fish that can be kept in an aquarium. The examples below are for small freshwater fish; larger freshwater fishes and most marine fishes need much more generous allowances.

Experienced aquarists warn against applying these rules too strictly because they do not consider other important issues such as growth rate, activity level, social behaviour, filtration capacity, total biomass of plant life, and so on.

This is because fish of different sizes produce quite differing amounts of waste. Establishing maximum capacity is often a matter of slowly adding fish and monitoring water quality over time, following a trial and error approach.

One variable is differences between fish. Smaller fish consume more oxygen per gram of body weight than larger fish. Labyrinth fish can breathe atmospheric oxygen and do not need as much surface area however, some of these fish are territorial, and do not appreciate crowding.

Barbs also require more surface area than tetras of comparable size. Oxygen exchange at the surface is an important constraint, and thus the surface area of the aquarium matters.

Some aquarists claim that a deeper aquarium holds no more fish than a shallower aquarium with the same surface area. The capacity can be improved by surface movement and water circulation such as through aeration, which not only improves oxygen exchange, but also waste decomposition rates.

Waste density is another variable. Decomposition in solution consumes oxygen. Oxygen dissolves less readily in warmer water; this is a double-edged sword since warmer temperatures make fish more active, so they consume more oxygen.

For instance, predatory fish are usually not kept with small, passive species, and territorial fish are often unsuitable tankmates for shoaling species.

Furthermore, fish tend to fare better if given tanks conducive to their size. That is, large fish need large tanks and small fish can do well in smaller tanks.

Lastly, the tank can become overcrowded without being overstocked. In other words, the aquarium can be suitable with regard to filtration capacity, oxygen load, and water, yet still be so crowded that the inhabitants are uncomfortable.

For planted freshwater aquariums, it is also important to maintain a balance between the duration and quality of light, the amount of plants, CO 2 and nutrients.

For a given amount of light, if there is insufficient number of plants or insufficient CO 2 to support the growth of those plants, so as to consume all the nutrients in the tank, the result would be algae growth.

While there are fishes and invertebrates that could be introduced in the tank to clean up this algae, the ideal solution would be to find the optimal balance between the above-mentioned factors.

Supplemental CO 2 can be provided, [70] whose quantity has to be carefully regulated, as too much CO 2 may harm the fishes. From the outdoor ponds and glass jars of antiquity, modern aquaria have evolved into a wide range of specialized systems.

Individual aquaria can vary in size from a small bowl large enough for only a single small fish, to the huge public aquaria that can simulate entire marine ecosystems.

One way to classify aquaria is by salinity. Freshwater aquaria are the most popular due to their lower cost. Marine aquaria frequently feature a diverse range of invertebrates in addition to species of fish.

Subtypes exist within these types, such as the reef aquarium , a typically smaller marine aquarium that houses coral. Another classification is by temperature range.

Many aquarists choose a tropical aquarium because tropical fish tend to be more colorful. Aquaria may be grouped by their species selection. The community tank is the most common today, where several non-aggressive species live peacefully.

In these aquaria, the fish, invertebrates , and plants probably do not originate from the same geographic region, but tolerate similar water conditions.

Aggressive tanks, in contrast, house a limited number of species that can be aggressive toward other fish, or are able to withstand aggression well.

Most marine tanks and tanks housing cichlids have to take the aggressiveness of the desired species into account when stocking.

This type is useful for fish that cannot coexist with other fish, such as the electric eel , as an extreme example. Some tanks of this sort are used simply to house adults for breeding.

Ecotype, ecotope, or biotope aquaria is another type based on species selection. In it, an aquarist attempts to simulate a specific natural ecosystem, assembling fish, invertebrate species, plants, decorations and water conditions all found in that ecosystem.

These biotope aquaria are the most sophisticated hobby aquaria; public aquaria use this approach whenever possible.

This approach best simulates the experience of observing in the wild. Most public aquarium facilities feature a number of smaller aquaria, as well those too large for home aquarists.

The largest tanks hold millions of gallons of water and can house large species, including sharks or beluga whales. Dolphinaria are specifically for dolphins.

Aquatic and semiaquatic animals, including otters and penguins , may also be kept by public aquaria. Public aquaria may also be included in larger establishments such as a marine mammal park or a marine park.

A virtual aquarium is a computer program which uses 3D graphics to reproduce an aquarium on a personal computer. The swimming fish are rendered in real time , while the background of the tank is usually static.

Objects on the floor of the tank may be mapped in simple planes so that the fish may appear to swim both in front and behind them, but a relatively simple 3D map of the general shape of such objects may be used to allow the light and ripples on the surface of the water to cast realistic shadows.

Bubbles and water noises are common for virtual aquariums, which are often used as screensavers. The number of each type of fish can usually be selected, often including other animals like starfish , jellyfish , seahorses , and even sea turtles.

Most companies that produce virtual aquarium software also offer other types of fish for sale via Internet download.

Other objects found in an aquarium can also be added and rearranged on some software, like treasure chests and giant clams that open and close with air bubbles, or a bobbing diver.

There are also usually features that allow the user to tap on the glass or put food in the top, both of which the fish will react to.

Some also have the ability to allow the user to edit fish and other objects to create new varieties. From Wikipedia, the free encyclopedia.

One night Mia secretly witnesses Conor and Joanne having sex. Mia then goes back to her room and slams the door several times.

Mia sends in her tape and is invited by the club to perform in person. Late one night, with Joanne passed out drunk upstairs, and after Mia and Conor have both been drinking, he asks to see her dance routine in the living room.

The following morning, Mia hears her mother crying; Tyler tells her that Conor has left. Mia tracks him down to his home in Chadwell St Mary and confronts him.

He explains that he cannot see Mia any more because of her age. He drives her to Tilbury Town railway station and provides her fare.

Finding a video camera and watching it, she discovers footage that reveals Conor has a wife and young daughter, Keira. Mia then urinates on the living room floor and, hearing the family return, sneaks out of the back door.

After going out into the fields and reaching the River Thames , Keira tries to escape. Mia catches up with her, but in the struggle, Mia throws Keira into the turbulent river water; she disappears and then resurfaces, after which Mia pulls her out and takes her home.

Mia runs away and Conor chases her over a field; when he catches up with her, he slaps her, knocking her to the ground, and then walks away without saying a word.

The next day, Mia goes to her audition. It is immediately obvious that it is for erotic dancers. The other participants are all grown women wearing heavy makeup and provocative clothing.

Mia takes the stage wearing a hoodie, but as the music starts, she walks off before performing her routine. Mia goes in search of Billy.

When she arrives at his place, Billy tells her that the horse had to be put down. Mia sinks to the ground in tears. Billy says he is moving to Cardiff , Wales, and invites her to join him.

Mia returns home to pack. Her mother tells her "go on then, fuck off" by way of a goodbye. The two set off for Wales as Tyler chases after the car.

Katie Jarvis , who plays Mia, had no prior acting experience. Principal photography began 28 July over the course of six weeks, [9] and was filmed in chronological order.

At the end of each week the actors were given the scripts for the scenes that they would perform the following week, so that when they performed each scene they were largely unaware of what would happen to their characters later in the film.

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.
