The use of aerators in fish ponds is one of the technical measures to increase dissolved oxygen in the water and prevent fish from floating. How to improve the effect of the use of the aerator, the introduction method is as follows:

First, if there is a small amount of fish floating in the fish pond, the aerator should be started around midnight before the fish float, and the aerator should be turned on continuously until the sun comes out.

Second, on a cloudy and rainy day, it can be turned on at 3-5 in the morning the next day, and it will be open until the sunrise in the east. For fish ponds with dense water, fat and fish, the start-up time should be appropriately advanced.

Third, in the high temperature season, in order to break the hot water layer, it is generally turned on at about 2 pm, and the boot time is 1.5-2.5 hours.

Fourth, the principle of using the aerator is that it is not necessary to turn it on in low temperature weather, and it can be turned on every day in order to break the hot water layer in high temperature weather. In order to increase oxygen directly, the time of starting the machine should be mainly at night, and it is generally not turned on in the evening. It should not be turned on during the day on cloudy and rainy days, and it should be turned on at night before the sun comes out.
