When the water in the fish tank is muddy, the first thing to do is to change the water, because poor water quality is most likely to cause fish to get sick, and changing the water is the fastest way to improve the water quality. It should be noted that the water can not be changed completely, up to one third, too much will stimulate the fish body, which is not conducive to its growth. In addition, but also according to the time of water turbidity to change the interval of water, muddy fast for a little more frequently.
Although the water change is immediate, but more or less for the fish is also affected, want to keep the water quality clear, the best way is to strengthen the filtration. Filtration is generally based on the size of the fish tank to match, the flow is about 5-10 times the volume of water. In addition, there are many kinds of filters, their functions are often different, physical filtration and biological filtration are necessary, and others can be added as appropriate.
Most of the time, the turbidity of the water in the fish tank is biological turbidity, which is caused by the proliferation of microorganisms, indicating that the water body is too fat. The reason why the water body is too fat is that there are too many baits and a lot of fish in the tank. By reducing feeding, the reproduction rate of microorganisms can be slowed down, which can also curb the deterioration of water bodies.
There is also a kind of turbidity caused by algae. This kind of water is generally green. Although green water is harmless to fish, it reduces the ornamental value. Want to make green water clear, generally can use germicidal lamp, can also use coagulant or algaecide, need to pay attention to the drug algae removal has a certain risk, must control the dosage.
