Fish can put potassium permanganate in the fish tank, but not directly. Instead, it should be diluted into a solution and poured evenly into the tank. Potassium permanganate, as a disinfectant, can kill bacteria in the tank, but not only harmful bacteria, but also beneficial bacteria, so the dosage must be controlled before use, otherwise it will cause damage to the ecosystem in the tank, and also pose a threat to the health of fish.
different concentrations of potassium permanganate 1, 5%: 5% concentration of potassium permanganate is generally used to disinfect the fish tank, because the concentration is extremely high, fish can not adapt, so it is best to fish it out before use, in order to avoid adverse reactions. Pour it into the fish tank and soak it for 1 hour, then drain the water, and then rinse it several times with clean water.
2, 3%: The concentration of 3% is also relatively high. Generally, it can only be used to treat fish, and the medicine can not be directly poured into the jar. It is necessary to prepare a special container, add water and stir it evenly, and then put the sick fish in it for 15-20 minutes. In the process, it should be observed all the time, and if there is discomfort, it needs to be fished out as soon as possible.
3. 1 ppm: 1 ppm means one in a million. This concentration of potassium permanganate will not do great harm to fish. Generally, after adding water, it can be directly poured into the fish tank, thus playing the role of sterilization and disinfection.
