The fish pond with fish can be disinfected with bleaching powder. When bleach is sprinkled into water, it produces chemicals such as hypochlorous acid, which can disinfect because it can release biological oxygen. It should be noted that this drug will decompose when it encounters air, and it is also harmful to the human body, so we should pay attention to preservation at ordinary times, and we must be careful when sprinkling the whole pond.
