The water used for fish farming cannot be directly used as tap water. This is the same reason as not being able to directly use tap water to water flowers. Because tap water has been disinfected, there will be residual chlorine in the process, which is a very deadly substance for fish. Therefore, the water must be aired first. The method of drying water is also very simple, mainly put the water in the sunny place to insolate, generally to insolate 3-7 days.
After pouring water into the fish tank, a nitrification system needs to be established. Fish tank is a small ecological environment, must have a good cycle, so that the fish can live a healthy life. Normally, the nitrification system is set up automatically, but this process is very slow and other problems may be encountered. So for first-time fish farmers, it would be safer to build a nitrification system in advance. Pour the nitrifying bacteria into the fish tank and add a little fish food afterwards. The purpose of doing so is that heterotrophic bacteria decompose organic matter and produce ammonia nitrogen, thus providing raw materials for nitrifying bacteria. In order to promote its reproduction, it is necessary to turn off the lights and explode oxygen during this period. Usually, the water will first become cloudy and then clear, which means that it has been completed.
In order to ensure that the water in the fish tank is suitable for the fish to live in, you need to put a few fish into the tank to test the water first. The time to test the water is usually about half a month, and it takes seven days for a few. As long as the fish do not get sick or die during the water test, it means that there is no problem with the water quality and the fish can be released. If the fish in the tank is dead, it needs to open the tank again to raise water.
