The fish pond needs to be turned on and off according to the season and water temperature to provide enough oxygen for the fish to breathe. Specifically, in general, as long as the dissolved oxygen content in the water is less than 5mg l, the aerator should be turned on to maintain the normal physiological activities and healthy growth of the fish.
For different seasons and water temperatures, in general, you can refer to the following suggestions:
1.Spring: When the water temperature is lower than 15, the metabolism of the fish slows down, and the number of feedings and feeding needs to be reduced, and the aerator can moderately shorten the running time or not turn on.
2.Summer: Summer is the peak period for fish growth and reproduction, the water temperature is between 20-30, it is recommended to turn on the aerator 24 hours a day to meet the oxygen demand of the fish and maintain a stable water quality.
3.Autumn: When the water temperature gradually decreases, the running time of the aerator can be moderately shortened, and it is generally recommended to turn on it in the morning and evening when the oxygen demand is at its peak, such as 4-6 am and 5-6 pm.
4.Winter: When the water temperature is lower than 10, the metabolism of the fish slows down and the appetite is reduced, at this time, the aerator can be turned off or the running time can be moderately reduced, but it should also be adjusted according to the actual water quality conditions.
In general, whether the fish pond can open an aerator or not depends mainly on the water quality and the needs of the fish. It is recommended to regularly check the water quality and the growth of the fish, and take timely measures to ensure the healthy growth of the fish.
