How to prepare water for fish farming

To raise fish, raise water first. Tap water should be left to dry for at least a day before the chloride in the water evaporates before use. The water temperature must be the same as the water temperature in the tank before changing, otherwise it will cause a stress reaction in the fish, which may cause illness or even death. You can put 1/2 millionth of coarse salt in the water to help reduce the occurrence of diseases.

If it is your first time to raise fish, remember to add trapped water to the empty tank, then add decomposed bacteria, usually pour it on the filter cotton, and then turn on the circulation pump and heat. The rod circulates normally for about two days and observe whether the water is clear and transparent, which indicates that the nitrification system has been established. At this time, pour the purchased fish into the tank.
