The turbid water after putting sand in the fish tank indicates that the sand itself has not been washed clean, and there are certain impurities on it. However, this kind of turbid water is physically turbid and does little harm. As long as the filter is opened for a day, it can basically absorb the suspended particles in the water, thus making the water clear.
1. Strengthen filtration: There are many reasons for the turbidity of fish tank water, but the first step to solve the problem is to strengthen filtration. No matter what kind of turbidity, it can be properly improved through filtration. However, the filtration system will also have problems for a long time, usually regular cleaning or replacement of filter cotton, but do not wash the filter material casually, which will destroy the original nitrification system, the harm to fish is greater.
2. Change water regularly: It is necessary to change water regularly for fish farming. If the water body is turbid, the frequency of water change can be increased appropriately. No matter what the object suspended in the water body is, frequent water exchange can effectively improve, but too much water exchange will stimulate the fish, will also play a certain reaction, so we need to strictly control the amount of water, do not change too much each time.
3. Establishment of nitrification system: In fact, the establishment of nitrification system can not improve the phenomenon of water turbidity, but water turbidity is a kind of appearance. If it is biological turbidity, if there are too many of them, the decomposition rate of organic matter will increase, thus greatly increasing the content of ammonia nitrogen in water. Nitrifying bacteria can convert ammonia nitrogen into nitrate which is harmless to fish, so it is necessary to establish a nitrification system.
