for the first time? 1. Disinfection: If you raise fish for the first time, you need to disinfect it first. The purpose of disinfection is to avoid some harmful bacteria hidden in the tank, which is harmful to the health of fish, so it is necessary to inject appropriate amount of water, add potassium permanganate, and soak the inner wall of the tank for about an hour. It can also be wiped with a cloth dipped in potassium permanganate solution and rinsed with clean water.
2. Bacteria cultivation: Water is needed for fish farming, and the most important thing for water farming is bacteria cultivation, which is to cultivate nitrifying bacteria. After injecting the trapped tap water, it is necessary to turn on the filtration and oxygenation equipment, then pour in the nitrifying bacteria culture solution, and turn off the light for a period of time to accelerate its reproduction. When the water in the fish tank is muddy and clear, you can prepare to raise fish.
3. Release the fish: To be on the safe side, you should first release some fish that break into the tank to test the water. Usually, you should choose some fish that are solid, easy to raise and cheap. It is no problem to raise them for one to two weeks before you can pour the fish you want into the tank. If a large number of fish die in the tank, it means that the water body is not good and the tank needs to be re-opened to raise water. Do
Old fish tanks also need to be opened. As long as the fish tank does not raise fish for a long time, it must be opened to raise fish again, but as long as the old fish tank has not touched dirty things, it can be simply washed without disinfection. But water is essential, only when the water is well raised, the fish can live, otherwise it is necessary to change a batch of fish regularly.
