the old fish tank 1. Disinfection: The old fish tank also needs to be disinfected, but it is not necessary. If you don't know what you've let go before, it's safer to disinfect it. Prepare some potassium permanganate, mix it into a solution and pour it into the fish tank, soak it for a few hours to complete the disinfection.
2. Raise water: The second step of opening the tank is to raise water, and the most important thing to raise water is to cultivate bacteria. The so-called culture is to cultivate nitrifying bacteria. This is a kind of beneficial bacteria, which can convert ammonia nitrogen into nitrate in the water body, thus avoiding the poisoning of fish. Usually in the first month, nitrifying bacteria should be added to the tank every week, and the lights should be turned off to explode oxygen.
3. Release the fish: In the process of cultivating bacteria, the water will become turbid first, and then return to clear, and then the fish can be released. However, to be on the safe side, it is best to put a few fish into the tank to test the water, and after half a month, you can put the fish you really want to raise.
