fish ponds with water and fish? If fish ponds have water and fish, they can be disinfected with chlorine dioxide. This drug is the mainstream disinfectant at present, not only has good effect, but also has low dosage, and will not produce any side effects. Hanging bags can also be used for disinfection. 3-6 bags are hung on the shelf of the fish pond, which are filled with 5 grams of copper sulfate and 2 grams of ferrous sulfate. Hanging bags should be hung for three days, and it is better to change the medicine once a day.
disinfectant to use? 1. Quicklime: Quicklime is a commonly used disinfectant, which is usually used when cleaning ponds. It will become a strong alkali when it meets water, and it will also emit heat, thus playing a bactericidal effect. The amount of medication depends on whether there is water, if there is no water, 70-80 kg per mu can be used, if there is water, 100-150 kg per mu per meter should be used.
2. Bleaching powder: Similar to quicklime, bleaching powder is a disinfectant used to clear the pond. Its effect is also very good, and the dosage is less than that of quicklime. However, its stability is poor, the difficulty of preservation is higher, not only to avoid light and heat, but also to prevent moisture, otherwise it will fail.
3. Chlorine dioxide: Chlorine dioxide is a new type of disinfectant. Its dosage is not much, and its effect is very good. It can decompose the protein of microorganisms, thus eliminating them. It can not only sterilize, but also be effective for algae and protozoa. Usually, the concentration used should be controlled at about 0.5-2 ppm.
