Do fish ponds need to use aerators (air suspension high-speed fans) in autumn?

In autumn, there is a large temperature difference between day and night, and the water quality changes relatively quickly. Due to temperature changes, algae in the water reproduce vigorously without high temperatures.

So it is easy to cause hypoxia at night. At this time, it is appropriate to turn on the oxygen concentrator for oxygenation, turn it on frequently during the day, and turn it on early at night.
