the fish tank 1. Fishing for fish and releasing water: Before preparing to sterilize the fish tank, fish out all the fish inside, otherwise it may cause phytotoxicity. After fishing out the fish, we need to empty the water in the tank, and at the same time, we need to take out the equipment in the tank and empty the whole fish tank, so that sterilization is safer.
2. Clean and sterilize: After everything in the fish tank is empty, you need to clean it. If there is algae, you can use an algae scraper to scrape the algae on it. Then you can inject water and pour in a proper amount of potassium permanganate for sterilization, usually soaking for 1-2 hours.
3. Rewatering: After soaking and sterilization, the drug needs to be discharged, and then rinsed several times with clean water. Because the water in the original tank has been poured out, it is necessary to re-raise the water, inject the trapped tap water, filter the oxygen for a period of time, and then put the fish into it.
