Since it is to re-open the tank, the first step is to disinfect it. Empty the water in the tank, and take out the filtering and other equipment. Do not put any more things in the fish tank. When the tank is empty, fill it with water, then pour potassium permanganate and other disinfectants into the tank and soak it for 3-4 hours. After that, you can empty the water, then wash away the residual drugs with clean water, and put them in the sun.
The second step of opening the jar is to raise water. Only when the water is well raised can the fish be well raised. Open the jar of water must be used to dry the tap water, if it is drying during the day, drying 1-2 days can be, if not put in the sun, it will take a week to dry. Pour the trapped water into the fish tank and add nitrifying bacteria into it, which can establish a nitrification system, thus avoiding excessive ammonia nitrogen in the water and poisoning the fish.
In the process of raising water, the water will generally become muddy first, and then return to clear, which shows that the water has been raised well, but in order to be on the safe side, it is best to put the fish in the tank to test the water first. Usually choose grass gold as a tank fish, its skin is good, and the temperature requirements are not high, can feed a week or two, you can put the fish you want to raise. If the fish in the tank die one after another, it means that the tank is not open well or there is a problem with the water, you can first find out the reason, and then think about the method.
