maintenance, care, compatibility
Have you ever heard that the water in the aquarium bloomed or turned green, and very quickly. What to do in this case?
First, you need to find out the reason, and second, learn how to deal with it.
Why is the water in the aquarium green? The reason is as follows: when blue-green algae reproduce, or euglena, to wait for the landscaping of the water.
You should know that these algae are single-celled and they float on the surface of the water in the form of an invisible film. Euglena is an important part of the food chain of the underwater world, and under the necessary conditions (reduction of nutrients, carbon dioxide and oxygen, a wide range of temperature conditions), it is rapidly multiplying.
It is not so easy to get rid of the flowering of water, given its sudden flashes. With strong light (green algae love it), with frequent renewal of water using chemicals, the biological filtration system of aquarium water gets lost, as a result of which euglena multiplies and grows.
How green algae appear in water – additional reasons
Why is the water green in the aquarium and how to deal with it?
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, power and type of filter, the presence of living plants, drifts, 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, which is consumed for the oxidation of organic matter, leads to an increase in the concentration of decomposition products.
The water becomes cloudy, gets the smell of hydrogen sulfide. But there are cases when it becomes green.
So why is the water green in the aquarium?
The reason for its turbidity is the mass reproduction of bacteria, and the water turns green usually from green microscopic euglenic algae that multiply in an aquarium. Euglena is normally always present in the aquarium, but during its reproduction, water “blooms”, which can be painted in yellow-green, green colors.
More often it is observed in aquariums with excessive brightness of the light source. Often, fans of ornamental fish, acquiring aquariums for the home, place them in the most convenient and cost-effective place – near the windows.
Direct intense sunlight contributes to the active reproduction in water of green algae, which cover the glass aquarium, decorations, plants. Strong artificial lighting also contributes to the reproduction of euglena.
It can be brought into the aquarium and with live food for fish from natural waters.
The first actions that are taken by novice aquarists are a complete replacement of water, cleaning plants, decorations. Similar, logical at first glance, events only aggravate the situation, causing bewilderment and the question of why the water is green in the aquarium, despite all efforts.
Changing water does not improve the situation. It is necessary to eliminate the causes of its “flowering” – turn off the light for a few days, shade the aquarium, located near the window.
After this, the regular change of water and cleaning of the soil will allow to correct the situation, since light and nutrients only stimulate the growth of green algae. Keep the aquarium clean at all times.
You should know that the process of water self-purification will accelerate with the addition of “old” water (1/3 of the total) to the aquarium, pre-stored, rich in humic acid and a set of microorganisms that help restore a healthy environment. You should know that it is harvested from a prosperous aquarium, not overcrowded with fish, with well-growing plants.
In order not to wonder about why the water is green in the aquarium, you can run daphnias into it. In this case, it is better to seed the fish so that they do not destroy the crustaceans.
You can also purify water with the help of special preparations acquired in pet stores. Algae die off when a solution of rivanol, trypaflavin, penicillin, streptomycin is added to the aquarium.
Special diatomaceous filters and UV sterilizers help to eliminate the “blooming” of water.
In order to no longer wonder why water is turning green in an aquarium, it is necessary to achieve the necessary biological balance for its aquarium inhabitants. To support it, you need to adjust the lighting: apply curtains, screens, change the power of the lamps. Remember that it is important where the aquariums are installed.
The fish will feel great with proper lighting, proper feeding, aeration and filtering.
It is useful to acquire new inhabitants of the underwater world who eat algae. These are pteregoplichts, antsitrusy, which remove plaque from glasses, mollies, Siamese seaweeds, Japanese shrimps, snails, ampouleries.
All the reasons why greens appear on the walls of the aquarium
The most common reason why greens appear on the walls of an aquarium is an excess of light. It may be too bright or too long. Direct rays of our Sun also have a negative effect on the state of water.
The light favors the active reproduction of the simplest (single-celled) algae, which first “plant” the liquid medium and then begin to grow on the inner surfaces of the aquarium.
To deal with this is very simple. Shade a fish house. If the greens on the walls of the aquarium have not yet fully tightened them, the breeding process will at least stop.
Snails and daphnids can destroy the attack. The latter must be run into the “pool” in such an amount that the fish do not have time to eat them.
And if you want to diversify the population of the aquarium, buy catfish – they do an excellent job with thickets on the walls.
Some aquarists believe that partial landscaping gives good results during landscaping – naturally, with filtration. This is not true.
On the contrary, such actions will lead to even greater growth of the green colony.
So far, they have been talking about unicellular unwanted “neighbors”. However, the most terrible enemy are multicellular – cyanophytes.
They are the reason why greens appear on the walls of the aquarium, with a bluish or brownish tinge. They begin to spread from the bottom, then they crawl along the walls and plants with unpleasant thick mucus.
They can also form floating islands, making it difficult for oxygen to enter the aquarium.
The nitrogen-containing compounds are to blame for cyanophytes, and again, an excess of light contributes to rapid reproduction. It is very difficult to remove these algae, it is better to prevent their generation.
First of all, it is necessary to plant many plants at once in a new aquarium, combining them with floating species that grow quickly (fit the elodea, nyas or pemphigus), it is better to lower the pH of the water to the mark 6. Algae-eating fish will also be very helpful in the difficult struggle. The smallest colonies of blue-green pests must be immediately cleaned. If you are lucky and if the process is not too running, you will win them.
If not, you will have to re-equip the aquarium.
The good news is that blue-green algae in a healthy glass house does not survive, so this attack happens quite rarely.
