? Chlorine dioxide is used to disinfect and sterilize fish ponds without hurting fish. There are many bactericidal drugs for fish ponds, the most common of which are quicklime, bleaching powder, etc. These drugs are usually used when the pond is cleaned before fish farming, and the effect is very good, but the residues must be washed away, otherwise it will cause some harm to fish. The advantage of chlorine dioxide is that it can play a good bactericidal effect at a very low dosage, and it is not harmful to fish.
are the bactericidal drugs used in fish ponds? 1. Quicklime: Quicklime is the best disinfectant for cleaning ponds. Its characteristic is that it becomes strong alkali when it meets water. At the same time, it can emit heat. In this way, it can eliminate bacteria, fungi and other hidden organisms in the water, so as to avoid harm to fish when raising fish in the future. A pond without water needs 50-74 kilograms per mu, and if there is water, it needs 125-150 kilograms. After the pond is cleared, it takes one to two weeks to release the fish.
2. Bleaching powder: Bleaching powder is also a commonly used disinfectant. It can be used with or without water in the pond. If there is no water, 7.5-10 kg per mu should be put. It needs to be diluted with water before it can be sprinkled on the whole pond. If there is water, 20 grams per mu will be used, and the fish will not be released until a week after the pond is cleared.
3. Chlorine dioxide: Chlorine dioxide is the mainstream disinfectant at present. It has almost no residue and the dosage is very low. It is usually used with citric acid. After the two are mixed, wait for 10 minutes and then use water to absorb water, which is 1.2-1.8 kg per mu.
