If you want to raise the water quality of fish well, you must first trap the water. Because most of the water used for fish farming is tap water, although this water is not polluted, a small amount of chlorine will remain in it after disinfection, and the residual chlorine can be volatilized by drying the trapped water. After that, it is necessary to keep filtering, which can filter out impurities in the water and make the water clear. In addition, attention should be paid to culture bacteria. After pouring nitrifying bacteria, turn off the lights and explode oxygen to accelerate its reproduction and establish nitrification system.

1. Change water: To improve water quality, the first thing you can do is change water. Changing water is an essential step in fish farming, which can not only improve the water environment, but also prevent diseases. However, the water should not be changed too frequently, usually once a week, and the amount of water should not exceed one third of the total amount, otherwise it will stimulate the fish.

2. Filtration: Although changing water is effective, it cannot be changed every day. Usually, improving water quality mainly depends on filtration. Filtering requires a filter, which can keep the water circulating, filter out various impurities in the water and improve the water quality. It should be noted that the filter materials cannot be easily cleaned and replaced, so as not to destroy the ecological balance.

3. Oxygenation: By oxygenating water, it can also improve water quality. Oxygenation can not only accelerate the reproduction of nitrifying bacteria, but also inhibit anaerobic bacteria, avoid water quality deterioration, and also prevent water body from rotting.
