to disinfect the fish pond? It is better to disinfect the fish pond 7-10 days before releasing the seedlings, and it must be in sunny days, because the effect will be affected in rainy days. Disinfection generally uses chlorine dioxide, its dosage is very small, and the effect of sterilization is very good, and the side effects of fish are relatively low, is the current mainstream disinfectant, usually used with citric acid. If you want to clean the pond, it is recommended to choose quicklime or bleaching powder, etc., which can not only destroy bacteria and fungi, but also clean up other harmful organisms.
is used for disinfection? 1. Quicklime: Quicklime is mostly used for pond cleaning and disinfection. It is relatively easy to obtain and the price is not high, so it is the best choice. After entering the water, this drug will produce chemical reactions, produce strong alkali substances, and emit a lot of heat, so that bacteria, fungi and protozoa in the water can be eliminated, usually about 125-150 kg per mu of fish pond.
2. Bleaching powder: The amount of bleaching powder is much less than that of quicklime. Its main component is calcium hypochlorite, which will produce a large amount of ecological oxygen when it meets water, thus achieving the effect of sterilization. Generally, 20 grams per cubic meter can be used, and its efficacy declines faster, so it is more suitable for fish farming in a hurry.
3. Tea dregs: Tea dregs are effective in disinfection. They are mainly used to kill some aquatic insects, snails and frog eggs. They do not kill bacteria and fungi, but also promote their growth. Therefore, they are suitable for use only under certain conditions.
