If the fish in the tank is dead, you'd better open the tank again. Because most of the fish in the tank are made of solid skin, the requirement for water quality is not high. If even this kind of fish can not adapt to it, it means that the water in the tank is not well raised, and other fish can not be raised alive, only to re-open the tank to raise water, and then use the fish in the tank to test the water.
1. Disinfection: The first step of opening the tank is disinfection. If it is a new fish tank, it is best to ventilate it first to disperse the smell of loose glue, and then start water injection disinfection. Fill the jar with water, pour in potassium permanganate, soak for three to four hours, then drain the water, and wash it several times to wash the medicine away.
2. Raising water: The most important thing to open the tank is to raise water. Not all kinds of water can be used to raise fish. Tap water is mostly used for raising fish at home. However, because it contains chlorine, a few fish need to be aired. After the residual chlorine is discharged, they can be injected into the fish tank. The water that has not been trapped can not raise fish, otherwise it will affect its health.
3. Cultivation of bacteria: Trapping water is only the beginning of water cultivation. The next thing to do is to cultivate bacteria. All kinds of beneficial bacteria are needed in the water to keep the water quality good. When cultivating bacteria, we need to turn off the light and explode oxygen, and put a little fish food, in addition, if we want to quickly establish a nitrification system, we can add a little nitrifying bacteria.
4. Test the water: When culturing the bacteria, the water will generally become turbid first, and then become clear. At this time, the water will be ready. However, to be on the safe side, it is best to test the water with the fish in the tank first. If it is no problem to raise the fish for half a month, then prepare to put in the fish you want to raise.
