The dissolved oxygen in the upper layer will be reduced

At this time, the sunshine intensity is weaker than that of cloudy days, and the photosynthesis of phytoplankton produces very little oxygen, so it must be turned on in the middle of the night to prevent pond fish from flooding. When adding new water to the pond, the outlet pipe is usually placed in the middle of the ridge, and the water is directly flushed into the pool.. 2. 4., Ltd. The above is a detailed introduction for everyone.

If a wide fixed wooden board is placed under the outlet pipe, it will not only slow down the flushing speed and impulse, but also make the injected new water splash on the board, greatly increasing the oxygen content of the injected water. It is necessary to understand how it works first, so that you can master its use in practice.

 

At this time, when the machine is turned on, the dissolved oxygen in the upper layer will be reduced and cannot be replenished, and the dissolved oxygen in the lower layer will be quickly consumed. Injecting water into a fish pond is usually a direct flow of water into the pond. Turn on in the early morning on a cloudy day.

Due to the large amount of washed water and the high flow rate, it is easy to jet aerator wash up the residual bait residue, fish excrement, and base fertilizer deposited on the bottom of the pond, which seriously pollutes the pond water and increases oxygen consumption. As a result, the oxygen consumption rate of the pool is accelerated. About the aquatic aerator 1. Start up in the middle of the night in continuous rainy weather. On a sunny day, the temperature difference between the water and the water is large, the water resistance is large, and the upper and lower water convection is very small, and the lower oxygen cannot be supplemented in time.
