's wrong with the long brown rust spots in the fish tank? The brown rust spots on the fish tank are brown algae. This kind of algae is not harmful when it is not abundant, and it can also provide some help to absorb nitrates and other substances in the water to prevent acidification of the water body. But if the algae burst, the situation is quite different, it must be removed in time, otherwise it will take up too much space, but also lead to a decrease in dissolved oxygen, thus killing the fish.
brown algae 1. Manual cleaning: The most immediate way to clean up brown algae is manual cleaning. Fish out the fish in the jar, drain part of the old water, and then wipe off the brown algae attached to the wall of the jar with a cloth. Although this method is fast, it can not cure the symptoms, and soon the brown algae will come back.
2. Fish cleaning: Regular cleaning of brown algae is very troublesome. If you want to save trouble, you can raise some algae-eating fish. The common ones are black line flying foxes, moss rats, elves and so on. They all have the habit of eating algae. With these fish, the algae in the fish tank will soon be cleaned up.
3. Drug cleaning: The so-called drug cleaning is to use various algaecides, usually glutaraldehyde or copper sulfate, both of which have good algaecide effect, but the dosage must be well controlled, otherwise it will cause side effects on fish.
