The first thing to do for a newly bought fish tank is to disinfect it to prevent harmful bacteria from remaining in the tank and causing harm to the health of the fish. The method of disinfection is very simple, first fill the water, then add potassium permanganate, soak for three to four hours, then drain the water, and rinse it with clean water several times.
If you want to raise fish well, you must first raise water well. Generally, the water used for fish farming at home is tap water, because the water contains residual chlorine, so it is necessary to deal with it before fish farming. After receiving the water, put it in a sunny place for a day or two, and then it can be used. After pouring into the fish tank, you can open the filter first and filter the water again.
To provide a good environment for fish farming, it is necessary to cultivate an ecological system. In the fish tank, not only the fish are needed, but also various beneficial bacteria are needed. They can transform some harmful substances in the water body, and the most common ones are nitrifying bacteria. Pour the prepared culture medicine into the tank, then turn off the light and explode oxygen, until the water is turbid and clear, you can start fish farming.
After the above steps, the water in the fish tank is already suitable for raising fish. However, to be on the safe side, it is best to find a few fish that break through the tank to test the water first. After putting the fish into it, raise them for half a month. If they do not get sick or die, they can raise other fish. If they die, they have to open the tank again.
