We can disinfect with quicklime. The principle is that quicklime produces extremely strong alkaline substances when it meets water, thus releasing a lot of heat, thus achieving the sterilization effect. But if you use quicklime to sterilize, there can be no fish in the fish pond, otherwise it will do great harm to the fish. Therefore, we usually disinfect fry with quicklime two weeks before stocking, and control the pond water level at about 8 cm during disinfection.
