Nitrifying bacteria capsules can be put directly into the fish tank, but in order to accelerate its growth and reproduction, it is best to open them and pour the contents into the fish tank. Nitrifying bacteria are indispensable beneficial bacteria in fish tank ecological environment. There are two kinds of nitrite bacteria, one is nitrite bacteria, which is responsible for converting ammonia nitrogen into nitrite. The other is nitric acid bacteria, which is responsible for converting nitrite into nitrate, thus preventing fish from being affected.

1. Cleaning and disinfection: Before using the bacteria house, it must be cleaned and disinfected. The purpose of doing this is to prevent it from bringing harmful bacteria into the fish tank, thus affecting the normal growth of fish. Potassium permanganate solution can be prepared, and the bacteria house can be soaked inside, and then washed with clear water after a period of time.

2. Pour bacteria: Although the nitrification system can be established sooner or later as long as the fish are raised for a long time, the fish may have problems in this process. Therefore, if you want to cultivate nitrifying bacteria as soon as possible, you can pour some regularly. Usually in the first month, add a little every week.

3. Turn off the lights and explode oxygen: Nitrifying bacteria belong to aerobic bacteria and don't like light very much. Therefore, in order to cultivate it, it is best to turn off the lights and explode oxygen, which can accelerate the growth and reproduction and facilitate the establishment of nitrification system.
