Quicklime is one of the most commonly used items in fish pond disinfection, generally used before fish farming. Its principle is to react chemically with water and produce a large amount of heat and strong alkali, thus killing bacteria in water. Generally, the whole pond is sprinkled, about 50-80 kg is needed for each mu, only 20-30 cm deep water is poured into the fish pond, after the whole pond is sprinkled, 3-5 days of insolation is carried out, and then new water is poured in, so that the sterilization effect is better.
Bleaching powder is also a relatively common disinfectant. This substance has a high chlorine content. When it reacts with water, it will produce hypochlorous acid and other chemical substances. Because it will release ecological oxygen, it can also effectively sterilize and disinfect. It should be noted that bleaching powder itself is harmful to human body, so be careful when splashing. Usually, about 20-30 kg per mu can be used, and if bleach is used, the dosage can be reduced by half.
Chlorine dioxide disinfection is currently the mainstream disinfection method, its advantage is that there is no residue, and as long as the content is very small, it can play a very good effect. Usually, this substance is used with citric acid. First mix the two in equal proportion, and then dilute them with water after 10 minutes. Generally, the dosage per mu is about 1200-1800 grams. It should be noted that water is needed to dilute the disinfectant in the disinfection process.
