Algae explosion in fish tanks is a common phenomenon, and the treatment methods are often different for different algae. If it is benthic diatom, it can be left untreated. This kind of algae is harmless to water quality and can be eaten by fish. If it is green water, it is necessary to change the water frequently and suspend feeding and fertilization at the same time. If it is green moss, it is necessary to raise some fish that eat algae, such as elves and black-line flying foxes. If it is black algae, it must be removed manually. First, benthic diatoms If the fish tank is placed in a dark place, some brown algae will grow at the bottom of the tank, which is benthic diatoms. This kind of algae is primitive and full of vitality. At first, it is a film, which can be wiped off with a brush. After a long time, it will turn green. But it is harmless in itself, but it doesn't look very beautiful. But also one of the fish foods, which contains certain nutrients and can be removed without cleaning.

Second, green water and green water are generally caused by excessive reproduction of single-celled green algae. The premise of this situation is suitable lighting environment and sufficient nutrients. The nutrients here are mainly nitrate and phosphate in the water, and their excess will make the water green. Green water is not a big problem. If you want to improve, just change the water frequently and suspend fertilization and feeding at the same time. It can also be sterilized by ultraviolet irradiation.

Third, green moss generally adheres to the wall of fish tanks and grows faster in places with good lighting conditions. It's light green at first, and then it will turn dark green. This kind of algae grows fast, it is difficult to wipe off, and it will affect the water quality after decay, so it must be removed as soon as possible. It can usually be solved by raising some fish that eat algae, such as elves, black flying foxes and white flying foxes.

Fourth, the black algae black algae is not good-looking, fish do not eat, and it belongs to algae that must be removed. Usually, Shui Rong leaves are easy to breed and need to be removed manually after being found. Wipe it when you see it, or you'll be in trouble if there are too many.
