Tap water can be used for fish farming. However, tap water can not be directly put into use. Before using tap water, a series of treatments are needed.
1. Chlorine removal: There is still some chlorine in the tap water, which has an adverse effect on the growth of fish. Therefore, before using tap water, it is necessary to keep tap water still or expose it to the sun for 1 to 2 days to remove chlorine.
2. Disinfection: Direct sunlight can effectively disinfect. You can also put some salt into the water, which can also play a role in sterilization and disinfection.
3. Nitrifying bacteria system culture: Fish will produce a lot of feces. Feces may be converted into toxic substances that affect their health. Therefore, before raising them, it is necessary to cultivate nitrifying bacteria system in water. That is, adding nitrifying bacteria to the water. This nitrifying bacteria can effectively treat feces.
4, clean water: fish also need to ensure that the water is clean. Therefore, attention should be paid to changing water when breeding, and it is better to install filters in the tank.
5. Oxygen: Fish need oxygen to grow. Therefore, the water they are raised in needs to ensure a certain oxygen content.
In addition, the pH and hardness of the water should be adjusted appropriately according to the habits of the fish. The best water is suitable for their growth.
Fish can use cool boiled water. Cool boiled water is more suitable for raising some fish that do not like hard water. Because the hardness of cold boiled water is relatively low. But there is a disadvantage of using cold boiled water to raise fish, that is, after boiling, the oxygen content in the water is very low. Therefore, if you want to use cold boiled water to raise fish, it is best to use an oxygen pump to input enough oxygen into the water.
