The fish tank no longer can be sold directly or given away. If there is a demand for glass, it can also be taken apart. However, the fish tank is generally made of glass adhesive, so it is difficult to ensure the integrity of the removed glass. If there is a free place, the fish tank can also be placed until you want to raise fish and then take it out. It should be noted that the old fish tank should be opened for reuse, and can not be stored in sunny places, which will reduce its service life.
1, disinfection: whether the old fish tank or new fish tank, open the tank need to be disinfected. The method of disinfection is very simple, first put the fish tank full of water, then add potassium permanganate, can also be disinfected with salt water, but the soaking time will be longer.

2, water: fish need water. First, put the water in the sunny place to dry, then pour it into the fish tank, turn on the filtering equipment, and let all the water filter again. Then we need to cultivate bacteria, pour nitrifying bacteria into the bacteria box, and turn off the light to establish a nitrification system, until the water is turbid and clear, you can prepare for fish farming.
3. Fish release: In order to ensure that the water quality can be used for fish farming, it is necessary to first test the water with some fish with solid skin. Usually, goldfish and other fish that are good for feeding are selected. If you are not sick for one to two weeks, you can release the fish.
