The first thing to do when opening the tank is to disinfect. If the fish tank itself contains bacteria, it will definitely affect the health of the fish. Generally, the newly bought fish tank only needs to be washed with clean water once, while the old fish tank needs to be disinfected. If you are not at ease, you can also fill the new fish tank with water, then pour potassium permanganate into it, soak it for several hours, then drain it, and then wash it with clean water once.
Raising water is very important for raising fish, because the fish tank must have a benign ecological cycle, so that the fish can grow healthily, otherwise it is easy to get sick and die. First, the tap water that has been aired for several days is injected into the fish tank, then nitrifying bacteria are poured in, and a little fish grain is put in, oxygen explosion lasts for 24 hours, and filtration should be opened at the same time. Usually, the water will become turbid first, and then it will gradually become clear, thus completing the water cultivation.
After the tank is sterilized and the water is well kept, the next step is to release the fish. But to be on the safe side, it's best to test the water with a few fish first. Water test fish must choose some good breed, extensive management can also live, if itself is not very good fish, then it is not easy to judge whether the water problem. As long as the fish in the water can survive safely for 15 days, other fish can be put into the tank.
