Raising water in an old fish tank is not faster than raising water in a new fish tank, because it also needs to go through the stages of disinfection, bacteria cultivation and water testing. According to the needs of raising fish, it usually takes about 7-14 days. If it is simply to change water and keep water, it will only take a day or two. After receiving the water, put it in a sunny place to bask in it, and when the chlorine volatilizes clean, it can be used to change the water for fish farming.
1. Disinfection: Because I don't know if the old fish tank has raised dead fish, so for the sake of insurance, it's best to disinfect it first. The method of disinfection is very simple, first fill the tank with water, then pour potassium permanganate, soak for several hours, then empty, and rinse with clean water several times.
2, water: fish must be good water. Usually, tap water that has been trapped for several days is injected into the fish tank, and then the filtration equipment is turned on to ensure that all the water is filtered again. Then pour in nitrifying bacteria, and turn off the light to explode oxygen, the purpose of doing so is to establish a nitrification system, until the water quality is turbid and clear, it means that the water is well maintained.
3, into the tank: ready to enter a few tank fish to test the water, usually choose a more solid variety, so that it is easy to determine whether the tank is the problem. It usually takes one to two weeks to test the water, and as long as the fish in the tank is OK, it can be replaced by other fish you want to raise.
