The new tank water 3 days can put fish, but to be on the safe side, it is best to put into the tank fish, that is, used to test the water of the fish. Fish farming must first raise water, because although tap water is not polluted, there are no beneficial bacteria, which is not conducive to the survival of fish. By raising water, the water body can become more suitable for the survival of fish.
1. Disinfection: Before keeping water in the new tank, the first step is to disinfect the fish tank. Whether it is an old or new cylinder, disinfection is very helpful. The method of disinfection is very simple, first fill the fish tank with water, then put in the right amount of potassium permanganate, soak it for 3-4 hours. Then drain the water and rinse it several times with clean water.
2. Bacteria cultivation: The most important part of water cultivation is bacteria cultivation, that is, various beneficial bacteria, the most important of which is nitrifying bacteria. There are two kinds of nitrifying bacteria, one can convert ammonia nitrogen into nitrite, the other can convert nitrite into nitrate, thus avoiding fish poisoning. Bacteria cultivation needs to pour nitrifying bacteria into the bacteria box, then turn off the light and explode oxygen, after a period of time, the water quality becomes turbid and then clear, which means that the nitrification system has been successfully established.
3. Test the water: After the bacteria culture is successful, you can test the water. Generally, use grass gold as the fish to enter the tank. Select a few relatively healthy fish to enter the tank and raise them for half a month. If there is no problem, you can put the fish you want to raise. If there is a problem, you have to change the water and try again. If it still doesn't work, you need to turn over the tank.
