All the reasons why greenery appears on the walls of the aquarium

Aquarium fish are the choice of many people. They are noiseless, do not litter, do not ask to walk at six in the morning and do not arrange for jumps on sleeping masters at three o'clock in the morning. In addition, the aquarium very animates the interior, it is very interesting to observe its inhabitants, and care of all this good is relatively simple.

However, quite often the "water house" starts to grieve its owner. The water becomes turbid, the walls begin to overgrow, an unpleasant odor may appear. There is a strong concern: will these harms not harm the residents of the glass house.

The first thing that comes to mind

The most common reason why greens appear on the walls of the aquarium is the excess of light. It can be too bright or too long. The direct rays of our Sun also have a negative impact 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 latter 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 when planting a good result gives a partial change of water - of course, with filtration. This is not true. On the contrary, such actions will lead to an even larger expansion of the green colony.

Hygiene and hygiene again!

The second most important factor, explaining why on the walls of the aquarium appears green, is a rare or careless cleaning it. The underfed food, the fallen leaves of underwater plants, the untimely uncleaned timbers 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 in the future reduce the amount.

If the walls of the aquarium are green, this may mean clogging up the filters or damaging the aeration equipment. To check both, it is necessary at least once a month, and for filters - even more often.

And if light is not enough?

In the first two cases described, a circumstance explaining why the greenery appears on the walls of the aquarium is redundant lighting: in the first directly, in the second, indirectly, stimulating rotting of underwater debris. And it's not difficult to cope with such a problem.

However, the plaque on the walls of the aquarium can cause so-called diatom algae, which, to their liking, is a 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 you can tear off from the glass, you can still, although with the risk of scratches, then from the plants in any way.

Diatoms look like yellow or brown flat formations. 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.

Multicellular evil

Until now, it was a question of unicellular undesirable "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. They begin to spread 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 cyanophytes are compounds containing nitrogen, and rapid 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 best lowered to 6. The algae fish will also help a lot in the 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-equiped.

The good news is that the blue-green algae in a healthy glass house do not survive, so this attack happens rarely.
