Reasonable use of fish pond aerators not only prevents and reduces floating heads, but also improves water quality, strengthens water circulation in ponds, weakens or eliminates harmful substances, and promotes plankton reproduction. So how do you use the aerator properly?
1. In summer, the fertilizer ponds are often deprived of oxygen due to excessive fish mouth and other organisms consuming oxygen, resulting in local or whole pond fish floating heads. Therefore, the aerator will be turned on at 1-2 o'clock in the middle of the night, and will be turned on until 7:00 in the morning of the next morning. After the sun comes out, the phytoplankton is used for photosynthesis to make oxygen, and the fish does not float until it stops.
2. When the "oxygen debt" is large, it is necessary to open the aerator. When the weather is high and the pond water temperature is high, a large amount of feeding will result in excessive water quality, low transparency, more organic matter in the water, large difference in oxygen between the upper and lower layers, and a large amount of “oxygen debt” in the lower layer. If the new water is not added for a long time, it will cause the water quality to be excessively degraded and cause the lack of oxygen to float the dead fish.
3. It is generally not advisable to turn on the wheel aerator in the evening. Because the photosynthesis of phytoplankton is about to stop, the oxygen can not be added to the water. After the start-up, the dissolved oxygen in the upper and lower layers is evenly distributed. The dissolved oxygen in the upper layer is not replenished, and the dissolved oxygen in the lower layer is quickly consumed. Accelerate the rate of dissolved oxygen consumption throughout the fish pond.
4. At noon on sunny days during high temperatures in summer and autumn, especially in fish ponds with fertile water and abundant phytoplankton, the impeller aerator should be turned on for 2-3 hours. Because in the sunny days of high temperature, the photosynthesis of phytoplankton is particularly strong, and a large amount of oxygen is generated. In fish ponds with water quality, the light can only reach a depth of 20-30 cm, so that the dissolved oxygen in the surface of the water body is saturated, and the bottom of the water body is dissolved. The oxygen is relatively low. The impeller aerator has the function of lifting water upwards, which can cause the vertical circulation of the fish pond water body during start-up, so that the dissolved oxygen of the whole fish pond water body is saturated, and plays the role of desalination, purification and improvement of water quality.
