pure water be used to raise fish

? Pure water cannot be used to raise fish. Although this kind of water is no problem to drink, but it lacks beneficial bacteria, and the oxygen content is not high, so fish farming is often not alive, using this kind of water is not as good as using tap water, tap water can be used as long as it is trapped for a few days, but the first fish farming water must be cultured in advance, establish a good nitrification system, it is best to pay attention to filtration and oxygenation, so as to better maintain water quality.

Trapped water: The first step in raising water is trapped water. There are many ways to trap water, such as drying, aeration, and some chlorine remover. But no matter which way, the purpose is the same, that is, to dissipate the chlorine in the water, so as to ensure the health of fish.

2. Oxygenation: Because fish need to breathe in the water, the dissolved oxygen in the water is also very important. In order to ensure sufficient oxygen, oxygenation can be carried out in the process of raising water. Prepare an oxygen pump, put the air head into the tank, and open it for 24 hours, so as to meet the needs of fish breathing.

3. Filtration: Good filtration is an important means to maintain the water quality. Therefore, attention should be paid to the filtration of water. The flow of the filtration equipment must be well controlled to ensure that all the water can be filtered about 7-10 times per hour, so as to keep the water quality good, which is conducive to the growth of fish.
