Aquarium (lat. aquarium ) — transparent container for permanent keeping of aquatic organisms.
It typically refers to a home aquarium (room) aquarium for keeping fish aquarium in home; for technical reasons, the maximum volume of such a tank is usually less than one cubic meter. Public aquariums . intended for demonstration to the audience of aquatic flora and fauna existing in the structure of zoos or as separate spectacular educational institution, can be up to 7500 m3 in volume.
To maintain the biological balance in the aquarium used a variety of tools: aerators, mechanical and biological filters. thermostats. thermometers and much more. Description simulation of the ecosystem in an enclosed artificial pond and various aspects of breeding fish deals aquarium.

Dimensions of aquariums
The size of the aquariums can vary in a wide range: from one to several thousand liters. Different species have different requirements for sizes of aquariums. Clear requirements for the minimum size, but there are a number of recommendations. For example, fish that are able to move very quickly and in nature they live in fast flowing rivers, require aquariums of large dimensions — approximately 10 times greater than the length of the body. Such fishes as stingrays. requires an aquarium with a large surface area of the bottom, fish the most important parameter of the tank can be depth. Some fish, however, very unpretentious — for example, chickens can live in tanks ranging in size from 0.5 liters.
In the aquarium more volume creates more stable and resilient ecosystem, which also owns the ability of self-purification and self-regulation. The smaller volume of water fits in the aquarium, the more noticeable changes in its quality — temperature, chemical composition, oxygen saturation, etc.
