Adding salt to the fish tank will not kill the nitrifying bacteria. Usually the nitrification system will not be established until about a week, so it is best for the owner to wait until the nitrification system is fully established before adding salt to the fish tank. Adding salt at this time will not have an impact on the nitrification system.

The role of nitrifying bacteria

1. Purify water quality: In the process of fish farming, it is very important to maintain good water quality. Nitrifying bacteria can decompose some organic matter and clean out impurities in the water, thereby improving water quality.

2. Reduce the ammonia concentration in the water: Sometimes there is a lot of ammonia in the breeding pond or water. At this time, nitrifying bacteria can reduce the ammonia concentration in the water and avoid the effects of ammonia on fish. Cause too much impact.

3. Adjust the balance of microorganisms in the water: Water contains many types of bacteria. It is very important to maintain the balance of microorganisms in the water. Nitrifying bacteria can play such a role.
