Aquarium – not only decoration of an interior, but first of all the ecosystem living under the laws, general for all ecosystems. It is steady when in it there is a biological and chemical balance. Balance violation affects appearance of an aquarium at once, and first of all water quality.
Why does water grow turbid?Turbidity of water in an aquarium, as a rule, is caused by mass development of various bacteria. From where do bacteria undertake? They, as well as other microbes, get in an aquarium with small fishes, with plants. Also soil, a forage for fishes and even air to which water contacts can be their source. Some quantity of bacteria is always present at each of ecosystem elements. In a certain quantity they are harmless to other inhabitants of an aquarium. At the same time water remains clear and transparent. You will surely face mass reproduction of bacteria in two-three days after filling of an aquarium fresh water. It is connected with the fact that in lack of enough other organisms of a bacterium begin to breed quickly. Externally it looks as light whitish or nacreous uniform dregs.
Process of reproduction of bacteria goes quicker if in an aquarium there are plants and soil.
Balance establishmentIn 3-5 days the turbidity disappears. It is explained by emergence in aquarian water of infusorians which intensively eat bacteria. There comes the moment of balance of an ecosystem. Only from this point in an aquarium it is possible to occupy fishes.
Plants need to be taken from an aquarium with healthy inhabitants.
Organic suspensionTurbidity of water in an aquarium where there are already fishes, can be caused by an organic suspension. The suspension is formed of waste products of fishes and plants and also at the wrong feeding and surplus of dry feeds. Aquarian filters, including biological in which the organic chemistry is actively absorbed by the bacteria living on filter material are used to fight against a suspension. Obligatory measures are also cleaning of a bottom, removal of the died-off parts of plants, the died organisms, excrement.
Violation of balance in the presence of fishes
Fast turbidity of water in an aquarium with the living fishes can be and manifestation of violation of balance and can be the first symptom of a disease of all of an ecosystem. For example, to precede a water zatsvetaniye. In this case the aquarium has large volume, frequent full change of water in it is inexpedient. It is easier to restore biological balance, having adjusted the light mode and having changed only a part of water. In big aquariums it is easier to maintain biological balance, than in small, but it is established longer. Good absorbers of dregs are vetvistousy Crustacea (water fleas, moina, basmina, etc.) which, eating bacteria, are a good forage for fishes. The obligatory factor of balance should be considered aeration and filtration of water. Filters need to be cleaned regularly.
