The fish tank generally uses potassium permanganate to disinfect.Although this substance is no longer used as a mainstream disinfectant, it is still widely used in fish farming.Disinfection method is also very simple, usually before preparing fish, first soak the fish tank with potassium permanganate solution, soak for 3-4 hours, empty the water inside, and then rinse with clean water several times to ensure that there is no drug residue.
1. Disinfection time: In the process of fish farming, it is generally not necessary to disinfect the fish. As long as the fish behaves normally, there is no need to consider this issue.But if the fish is sick, some conditions can be cured by disinfection in the early stage.In addition, if you buy a new fish to enter the tank, in order to avoid it carrying harmful bacteria, causing harm to healthy fish, also need to be disinfected.
2. Disinfection method: Potassium permanganate or salt water is usually used to disinfect the fish. The concentration of potassium permanganate is usually 20 ppm. Soak the fish in it and take it out after 2-3 minutes.If it is salt water, the concentration should not exceed 1%, and the soaking time should not be too long, so as not to cause it to dehydrate.
3. Precautions: Due to the different constitutions of fish, there may be different performances during disinfection. At this time, you must pay attention to observation. If you find that the fish is heterotrophic, you must fish it out in time and put it back into clean water for feeding, so as to avoid more serious situation.
