Aquarium fish are the choice of many people. They are noiseless, they do not litter, they do not ask to go for a walk at six in the morning and do not arrange jumps for sleeping masters at three o'clock in the morning. In addition, the aquarium very animates the interior, it is very interesting for its inhabitants to observe, and care of all this good is relatively simple.
However, not infrequently the "water house" begins stronglygrieve its owner. The water becomes cloudy, the walls begin to overgrow, an unpleasant odor may appear. There is great concern: will these unsympathetic manifestations harm the inhabitants of the glass house.
The most common reason whyThe walls of the aquarium appear green, - this is an excess of light. It can be too bright or too long. The direct rays of our Sun also have a negative effect on the state of water. Light favors the active reproduction of protozoa (unicellular) algae, which first "green" the liquid medium, and then begin to build up on the inner surfaces of the aquarium.
It is very easy to combat this. Pritenite fish house. If the greens on the walls of the aquarium have not yet fully tightened them, the process of reproduction will at least stop. Snails and daphnia can be destroyed. The last should be run into the "pool" in such a quantity that the fish do not have time to eat them. And if you want to diversify the population of the aquarium, buy catfish - they are coping well with thickets on the walls.
Some aquarists believe that whenLandscaping good results gives a partial change of water - naturally, with filtration. This is not true. On the contrary, such actions will lead to an even larger expansion of the green colony.
The second important factor, explaining,why on the walls of the aquarium appears greens, is a rare or careless cleaning it. The underfed food, the fallen leaves of underwater plants, the untreated sewage in time create comfortable conditions for the active growth of all the same unicellular algae. Most often such accumulation creates extra food. Observe the pets: if they did not eat the poured in a quarter of an hour, remove the remnants, and later reduce the amount.
If the walls of the aquarium are green, this can mean clogging up the filters or damaging the aeration equipment. You should check both, at least once a month, and for filters, even more often.
In the first two cases described,explaining why on the walls of the aquarium appears green, is the excess lighting: in the first directly, in the second - indirectly, stimulating the rotting of underwater debris. And it's not difficult to cope with such a problem.
However, plaque on the walls of the aquarium can causeso-called diatoms, which, to their liking, is the lack of light. Many "fish farmers" appear in winter, if there is no additional illumination, and with increasing daylight loss themselves. Such algae are unpleasant in that they stick to the surfaces almost tightly. If it is still possible to tear off the glass from the glass, even with the risk of scratching, then there is no way from the plants.
Diatoms look like yellow or brown flatformation. The first step is, naturally, an increase in illumination. However, if this did not help, then the reason is the presence in the aquarium water of a significant concentration of silicates. Accordingly, you will have to go to the pet store after the filter that absorbs them.
Until now, it was a question of unicellularunwanted "neighbors". However, the most terrible enemy is multicellular - cyanophytes. They are the reason why greens appear on the walls of the aquarium, with a bluish or brownish hue. Begins their spreading from the bottom, then they creep along the walls and plants with unpleasant dense mucus. Can form and floating islands, hindering the access of oxygen to the aquarium.
Guilty of the appearance of cyanophytic compounds,containing nitrogen, and fast reproduction is again facilitated by excess light. It is very difficult to remove these algae, it is better to prevent their generation. First of all, in a new aquarium, many plants must be planted at once, combining them with floating species that grow rapidly (fit elodea, nasas or pemphigus), the pH of the water is better reduced to 6. The algae fish will also help in a difficult struggle. The smallest colonies of blue-green pests must be cleaned immediately. If you are lucky and if the process is not too bad, you will defeat them. If not, the aquarium will have to be re-equipped.
The good news is that the blue-green algae in a healthy glass house do not survive, so this attack happens rarely.</ p>
