The aerator must first be operated under safe conditions, and at the same time, the start-up and running time should be determined in combination with the pond stocking density, growing season, pond water quality conditions, weather changes, and the working principle, performance, and load of the aerator.

One, look at the weather. It can be turned on in the afternoon when it is sunny, the next morning when it is cloudy, in the middle of the night when it rains continuously, and in the middle of the night when it rains heavily. It does not turn on after sunrise in the morning, does not turn on in the evening, and does not turn on during the day on cloudy and rainy days. If the sun is strong and the temperature is high during the day, and there is a sudden thunderstorm in the evening, it is necessary to open the fish pond aerator earlier and more often.

Second, look at the wind direction. In the case of a southerly wind blowing during the day, the temperature is very high, and the north wind suddenly turns to the north at night. When the temperature turns low, it is necessary to turn on the aerator for a few more hours to adjust and increase the oxygen.

Third, look at the season. Do not turn on or turn on less frequently in winter, and turn on more or more frequently when the temperature is high in summer and autumn. In case of continuous rain in summer, it is necessary to open more aerators. For example, in the fish growing season, turn on the machine for 0.5 to 1 hour at noon on a sunny day, which can stir the water and improve the water quality.

Fourth, look at oxygen debt. It has been sunny for a long time, and the water temperature of the pond is high. When the "oxygen debt" is large due to the large amount of feeding and the excretion of a large amount of fish, it is necessary to turn on more aerators.
Fifth, look at feeding. Open the aerator (especially eel, catfish, etc.) 1 to 2 hours before and after feeding the feed, which can agitate the water body of the fish pond and make the water body form a circulating flow. On the one hand, the taste of the feed is brought to all parts of the fish pond to attract food; on the other hand, the fish can develop the habit of eating in the food court.

Sixth, look at the time. Turn it on before dawn to increase and restore the dissolved oxygen in the water. Starting at 9-10 am, it can not only add oxygen to the water, but also promote the exchange of pool water, utilize the photosynthesis of phytoplankton, and increase the amount of dissolved oxygen in the pool water. When it is turned on at 3-5 p.m., it can directly supply oxygen to the water to meet the needs. The most important thing is to store a large amount of oxygen to meet the needs at night. In the summer fertilizer ponds, the aerators are turned on at 1-2 in the second half of the night, until the sun comes out at 7-8 in the next morning, and the phytoplankton conducts photosynthesis to generate oxygen, and the fish does not float before it stops.

Seven, see the temperature difference. When the temperature difference between the air temperature and the temperature of the pool water and the temperature of the upper and lower layers of the pool water is large, the machine should be turned on in time.

Eight, look at the pond. If the pond mouth is small, the water is low, the color of the pond water becomes poor, and the water bottoms out in cloudy and rainy days, in addition to adding new water in time, the aerator should be turned on in time.
