potassium permanganate open the jar to soak? Potassium permanganate open the jar to soak for 1 hour. This is a common disinfectant that can be used to disinfect fish tanks to avoid bacterial and fungal residues, which are harmful to the health of fish. First fill the fish tank with water, then pour it into it, soak it for 1 hour, then drain it, and rinse it several times with clean water. Because it is a strong oxidant, it will fail in more than 4 hours, and it will not have a greater effect after soaking for a long time.

Trapped water: The first step of raising water in a tank is to trap water, because tap water is generally used for fish farming. This kind of water is not polluted after disinfection, but there will be residual chlorine, which is harmful to the health of fish. Therefore, it is necessary to put the water in the sun and dry it for a few days so that the chlorine can volatilize.

2. Filtration: After the water is trapped, it can be injected into the fish tank. At this time, do not release the fish immediately. Turn on the filtration equipment first, and let the water body be filtered again and again. Because there may be some impurities in the water, they can be filtered out by filtration to make the water clearer.

3. Bacteria culture: In addition to filtration, bacteria should be properly cultured. Culture is the cultivation of nitrifying bacteria, which is very helpful to maintain water quality and avoid the poisoning of fish by ammonia nitrogen. Generally, in the first month, the right amount of culture medium should be poured in every week, and at the same time, the light should be turned off to explode oxygen, so that it can reproduce in large numbers.
