Because the width and height of a 1-meter fish tank are uncertain, the amount of water it contains is also uncertain. Generally, it is about 200-400 liters, that is, 200-400 kilograms of water. If it is to disinfect the fish tank, it needs 3-5% potassium permanganate, that is, about 6-20 kg. If it is to disinfect fish, the dosage is generally 1-2 ppm, which is converted to about 0.0002-0.0004 kg.
1, fish tank disinfection: potassium permanganate as a disinfectant, the most common use is to disinfect the fish tank. But this kind of disinfection is divided into two situations, one is disinfection when there is no fish, the other is disinfection when there is fish. When there is no fish, it should be soaked in 3-5% potassium permanganate for 39 minutes, and if there is fish, it is enough to add 0.5 ppm potassium permanganate.
2. Fish body disinfection: In addition to disinfecting the fish tank, potassium permanganate can also disinfect the fish body. The general concentration is 1-2ppm. It should be noted that the diluted solution must be poured into the fish tank. The medicine cannot be directly poured in, otherwise it will have adverse effects on the fish.
3. Treatment of fish disease: If the fish is sick, potassium permanganate is also needed for treatment. If the illness is mild, it can be soaked in 1-3% potassium permanganate solution for 15-20 minutes, if it is seriously ill, the concentration should be increased to about 5%, and after soaking, it should be kept quiet with clean water for a while before it can be put back into the original jar.
