to add salt to koi black spot disease? It is not very effective to use salt to treat koi black spot disease. Because black spot disease is mainly caused by poor water quality or lack of oxygen, if we want to treat black spot disease well, we must first improve the water quality. Adding salt to water can only change the osmotic pressure, although it can inhibit the growth of bacteria, but it can not play a direct therapeutic role.
? After koi suffers from black spot disease, the fish tank should be disinfected first. The koi can be fished out first, and then put in after cleaning up the fish tank. Then the filtration system in the fish tank should be cleaned, and the sulfuric acid solution can be used for disinfection after cleaning.
If the black spot disease of Koi is not serious, it can be treated by temperature difference. Breeders can use the heating rod to raise the temperature, then turn off the heating rod, and raise the temperature again after the temperature drops, and repeat several times to effectively treat the black spot disease. However, the change of temperature difference depends on the specific situation of Koi. Potassium permanganate solution medicated bath can also be used, once a day, 30 minutes each time. During the treatment period, the koi should be exposed to the sun as much as possible, and the feces should be cleaned up in time. It is better to change one third of the water every day, and it can be cured after a week or so.
