Self-purification of water in natural aquatic ecosystems occurs due to physicochemical and biological processes involving hydrobionts: living organisms and plants. The condition of the aquarium water depends on the organization of the system (maintenance mode, filter power and type, the presence of living plants, snags, the number of fish and food). The color of water can change under the influence of various factors. Thus, the low content of oxygen in it, consumed for the oxidation of organic matter, leads to an increase in the concentration of decomposition products. The water becomes cloudy, acquires the smell of hydrogen sulfide. But it is not uncommon for it to turn green. So why is the aquarium water green?
The reason for its turbidity is the mass reproduction of bacteria, and the water usually turns green from green microscopic euglena algae that have multiplied in the aquarium. Euglena is normally always present in the aquarium, but when it reproduces, the “blooming” of water begins, which can turn yellow-green, green. This is more often seen in aquariums with excessive brightness of the light source. Often loversdecorative fish, acquiring aquariums for the home, place them in the most convenient and "profitable" place - near the windows. Direct intense sunlight contributes to the active reproduction of green algae in the water, which cover the glass of the aquarium, decorations, and plants. Strong artificial lighting also promotes the reproduction of euglena. It can be brought into the aquarium and with live food for fish from natural reservoirs.
The first steps taken by novice aquarists are a complete water change, cleaning of plants, decorations. Such, logical at first glance, events only exacerbate the situation, causing bewilderment and the question of why the water in the aquarium turns green, despite all efforts.
Changing the water does not improve the situation. It is necessary to eliminate the causes of its “blooming” - turn off the light for several days, shade the aquarium, located not far from the window. After that, regular water changes and soil cleaning will correct the situation, since light and nutrients only stimulate the growth of green algae. It is necessary to monitor the cleanliness of the aquarium constantly.
You should know that the process of self-purification of water will be accelerated by adding "old" water (1/3 of the total volume) to the aquarium, which is pre-stored, rich in humic acid and a set of microorganisms that help restore a he althy environment. You should know that it is harvested from a safe aquarium, not overpopulated with fish, with well-growing plants.
In order not to wonder why the water in the aquarium turns green,you can run daphnia into it. At the same time, it is better to remove the fish so that they do not destroy the crustaceans.
You can also purify water with the help of special preparations purchased at pet stores. Algae die off when a solution of rivanol, tripaflavin, penicillin, streptomycin is added to the aquarium.
Special diatomaceous filters and UV sterilizers help to eliminate the "bloom" of water.
In order to no longer wonder why the water in the aquarium turns green, you need to achieve the necessary biological balance for your aquarium inhabitants. To support it, you need to adjust the lighting: use curtains, screens, change the power of the lamps. Remember that it is important where the aquariums are installed. Fish will thrive with proper lighting, proper feeding, aeration and filtration.
It is useful to acquire new inhabitants of the underwater world that eat algae. These are pterygoplichts, ancitruses that remove plaque from glasses, mollies, Siamese algae eaters, Japanese shrimps, ampoule snails.
