way to disinfect the newly dug fish pond? The best way to disinfect the newly dug fish pond is to use quicklime. You can also use bleaching powder or Qingtangling. Quicklime is a commonly used disinfectant, which can become a strong alkali in water, and can emit a lot of heat, thus killing bacteria, fungi and various harmful substances. It should be noted that it must not be used in fish farming, otherwise the fish will die, and chlorine dioxide is best used for disinfection during fish farming.
are the disinfectants? 1. Quicklime: Quicklime is a commonly used disinfectant. There are two kinds of disinfectants: dry disinfection and wet disinfection. New fish ponds usually use wet disinfection. First inject water into the fish pond, then use 80-100 kilograms of quicklime per mu per meter of water, emulsify it and sprinkle it into the pond while it is hot.
2. Bleaching powder: Bleaching powder, like quicklime, is a disinfectant used in the period of clearing the pond. It is rarely used at other times. Their usage is similar. It can be sprinkled on the whole pond after adding water, but the dosage is less than that of quicklime. It can be used 12-15 grams per mu. Do not touch it directly when using it. It is better to wear a glove.
3. Chlorine dioxide: Chlorine dioxide is a new type of disinfectant. Compared with traditional disinfectants, its dosage is better, and it is not harmful to fish. However, before use, it needs to be mixed with citric acid in a ratio of 1:1, diluted with water after 10 minutes, and then poured into the fish pond.
