How to use the aerator reasonably?

1. How to use the aerator reasonably:
The operation time of the aerator should be determined in combination with the accumulation density of fish in the pond, the growing season, the water quality of the pond, weather changes, and the load of the aerator, so as to ensure that there is no waste in the operation. Its use should follow the following principles:
1. Open at noon on sunny days
In the breeding high temperature season, in the case of continuous sunny days, the aerator should be started at noon. On continuous sunny days, the photosynthesis of phytoplankton is strong, and the dissolved oxygen content in the water is high, which will not affect the growth of fish. The purpose of starting the aerator is to adjust the overall dissolved oxygen state of the pool and increase the dissolved oxygen content in the middle and lower layers of the water. When the aeration was started at noon on a sunny day, the aerator accessories had no significant effect on water stirring. However, by stirring the water body to promote the mixing of the upper and lower water bodies, the upper and middle water bodies with high oxygen content in phytoplankton photosynthesis can be brought into the middle and lower water bodies to accelerate the decomposition of organic matter and avoid the decomposition of a large amount of dissolved organic matter under anaerobic conditions. , Eliminate potential oxygen consumption factors and effectively avoid the harm caused by the rapid decline of dissolved oxygen in the entire pool when the weather changes suddenly.
2. Open the door early the next day
In the high temperature season, when the daytime is cloudy and the light intensity is insufficient, the aerator should be started before sunrise the next day. On cloudy days, the light intensity is obviously weakened, the photosynthesis of phytoplankton is controlled, the increasing ability of oxygen in the water body is obviously reduced, and the total dissolved oxygen content of the pond is reduced. At night, phytoplankton photosynthesis, the main source of dissolved oxygen in aquaculture water, stopped, and dissolved oxygen in aquaculture water showed a downward trend, reaching a low point around sunrise the next day. Due to the cloudy day the day before, the total amount of dissolved oxygen in the water is low, and it is easy to lack oxygen at this time, which affects the normal activities of fish. Starting the aerator in advance to increase oxygen can effectively avoid the phenomenon of low dissolved oxygen in the water affecting aquaculture production
3. It rains in the middle of the night
In the high-temperature breeding season, if it rains continuously, according to the actual dissolved oxygen monitoring, the aerator should be started in the middle of the night. Under continuous rainy weather, the photosynthesis of aquaculture water was severely controlled, and the total oxygen content of the water was further reduced. At night, the oxygen content of the water body decreases rapidly due to fish activities, organic decomposition and other aquatic biological activities, and it is difficult to last until the sunrise the next day. Since the normal activity of the fish is affected by the low oxygen content, it is necessary to start oxygen enrichment and add oxygen to the machine as early as possible.
