time to open the fish pond aerator? The opening time of the fish pond aerator depends on the weather. It opens at noon on sunny days, in the morning on cloudy days and in the middle of the night on rainy days. The reason why it opens at noon on sunny days is that the temperature difference between the upper and lower water layers at noon is large, and the oxygen in the lower water layer can not be supplemented, so it is necessary to open the oxygenator to supplement oxygen. In cloudy days, the light intensity is low and the oxygen produced by photosynthesis is low, so it is necessary to turn on the oxygenator early, otherwise the fish will float around dawn. There is a lack of light in rainy days, so it will open in the middle of the night.
