For novice fish farmers, the biggest misunderstanding is that clean water can raise fish. Because the water looks very clear, there may also be some substances harmful to fish. For example, tap water looks very clean, but it is not good to use it directly to raise fish, which contains chlorine. If you want to turn it into water for fish, you need to dry it. Put the water in the sun for 24 hours, that is, 2-3 days. If you need water urgently and have no time to dry, you can also use explosive oxygen to remove chlorine, which only takes 2-3 hours.
Airing water is only the first step in water cultivation. To provide a good living environment, it is also necessary to have certain nitrifying bacteria in the water. This bacteria can remove ammonia and other harmful substances produced in the process of fish farming, which is very helpful to the health of fish. The method of cultivating it is also very simple, first of all, to ensure that the oxygen content in the water is high, secondly, there is a faster flow of water, at the same time, it needs to be adsorbed in some places, floating bacteria in the water is useless. Generally, the use of trickling filter box can make this kind of bacteria multiply rapidly.
We can't detect whether the water is good or not. If we put the fish directly, it may lead to its death. So at this time, we need some fish to test the water. This kind of fish is called run into the tank fish. Put it into the fish tank for a period of time to see if there is no problem, then you can put other fish in it. If the fish is sick or dead, it means that there is still a problem with the water quality and needs to be raised again.
