Generally speaking, what is the best time to increase oxygen in your own fish pond?

The best time to increase oxygen in fish ponds is noon on sunny days, early morning on cloudy days and midnight on rainy days. Turning on the aerator at noon on a sunny day can make the upper and lower water exchange, reduce the temperature difference and oxygen content, and replenish the oxygen in the lower water in time. Turning on the aerator in the cloudy morning can prevent the phenomenon of floating fish from appearing due to lack of oxygen in the water around dawn. You can turn on the aerator on rainy nights to prevent fish from drowning in the pond. Oxygen pumps in fish ponds generally operate 24 hours in summer and 3-5 hours in spring and summer.

Generally, the aerator should be turned on, because the temperature difference between day and night is large, the water quality changes rapidly, the algae reproduction is not ideal, and the pond may be deprived of oxygen at night, so it is more appropriate to supplement oxygen with the aerator. The oxygen generator is suitable for frequent start-up during the day, early start-up at night and start-up at noon during the day, lasting 1-2 hours. It is not suitable to start the aerator on a sunny night, because the phytoplankton has stopped supplying oxygen at this time, which will make the upper and lower water layers convection and cause fish schools.

Generally 10 months requires oxygen. 10 has entered autumn, the temperature difference between day and night is large, the water quality changes rapidly, algae reproduction is not as vigorous as high temperature weather, and hypoxia may occur at night. At this time, an aerator can be used to supplement oxygen appropriately. The aerator is suitable for frequent start during the day and early start at night. During the day and at noon, appropriately increase oxygen and turn on 1-2 hours. After oxygenation, the water quality can be improved and the floating head phenomenon of fish can be inhibited. It is not advisable to turn on the aerator at night on a sunny day. This will consume oxygen in the water (phytoplankton will stop photosynthesis and reduce dissolved oxygen in the upper water), resulting in convection and floating fish.

If the weather is sultry, the start-up time of the oxygen generator can be appropriately extended; If the weather is cool, the aeration time can be shortened. In case of continuous rainy days, the pond lacks sunshine for a long time, which leads to the difficulty of photosynthesis of phytoplankton and the decrease of oxygen production. At this time, the oxygen generator should be turned on in the middle of the night to prevent the fish from being flooded. If the pond is fertilized, the time to start the oxygen generator should be appropriately extended, otherwise it should be shortened. If the wind is low, it is necessary to appropriately extend the time to start the aerator, otherwise it will be shortened. Usually, the fish pond can be oxygenated for a period of time, which can improve the water quality and increase dissolved oxygen. If pesticides are used in fish ponds after spring, but the dissolved oxygen in the water is insufficient, it is necessary to start the oxygen generator in time to replenish oxygen.
