for fish tanks? It is better to use potassium permanganate to disinfect and sterilize fish tanks. Potassium permanganate is a commonly used disinfectant, which has strong oxidation, so it can kill a variety of bacteria and fungi, and as a traditional disinfectant, its dosage is relatively clear, so it will not have side effects. However, there are many new disinfectants, some of which are less effective, but the price is also more expensive, such as chlorine dioxide is one of the representatives.
is the concentration of potassium permanganate? 1. 3-5%: 3-5% potassium permanganate belongs to the category of high concentration, which is generally used only when disinfecting fish tanks. Before disinfection, fish should be fished out first, and the contents should be removed together, then new water should be injected and potassium permanganate should be poured in, and soaked for about 1-2 hours.
2. 1-3%: The concentration of 1-3% potassium permanganate is slightly lower, but it is still a certain risk for fish, so it can not be poured directly into the tank. Usually this concentration is used to treat fish disease, according to the severity of the disease to determine the concentration of drugs, soaking time is generally 15-20 minutes.
3. 1-2 ppm: If disinfection is needed when raising fish, the concentration of potassium permanganate is generally 1-2 ppm. This concentration of drugs has a bactericidal effect on fish, and the harm is not great, so don't worry. If it is still high, it can also be reduced to about 0.5 ppm.
