To make the water clear, the first thing you need is filtration, which has a very good effect on delaying the deterioration of water quality. Usually, choose the right filter according to the size of the fish tank. There are many kinds of filters and different filtration methods. Generally, physical filtration and biological filtration are needed. Physical filtration is mainly to remove dirt and particles in the tank, while biological filtration can decompose and reuse the substances polluting the water body.
No matter how good the filtration is, the condition of the water body will also deteriorate. At this time, it is necessary to change the water. Changing water is a more immediate method, after discharging part of the water, add new water, so as to improve the water quality. It should be noted that water should not be changed too frequently, which will stimulate the fish and affect its health and survival. Do not change more water each time, and keep it at about a quarter.
The purpose of bacteria culture is to cultivate beneficial bacteria such as nitrifying bacteria. Although it can not improve the turbidity of water, when water is mixed, it is often accompanied by the increase of ammonia nitrogen in water, which is harmful to fish, nitrifying bacteria can convert it into nitrite and nitrate, which can be absorbed by aquatic plants, thus improving water quality.
The fish tank becomes turbid, mainly because there are too many microorganisms in the tank, and their reproduction depends on the organic matter in the water, mainly including residual bait and fish feces. By reducing feeding, the amount of organic matter can be controlled to avoid excessive reproduction of microorganisms, thus playing the role of preventing water turbidity.
