Many farmers have a big misconception about the amount of dissolved oxygen in the water, it is believed that aquatic plants and algae can perform photosynthesis and provide dissolved oxygen. As long as there is the sun, the water will not lack oxygen. Let's take a look at how to use the aerator correctly.

We all know that aerators can agitate the water layer and help the oxygen in the air blend into the water. However, aerators also play a more important role in convecting the upper and lower waters, exchanging the oxygen-rich dissolved water in the upper layer with the bottom water, thereby preventing a series of problems caused by excessive hypoxia in the bottom water.

When is the right time to start the aerator? It is mainly divided into three time periods.

(1) Sunny noon

On a clear day, noon is the time period when the photosynthesis of algae and aquatic plants in the water body is strong, so the upper and lower water bodies should flow. This not only prevents oxygen depletion in the bottom water, but also prevents the water body from heating up too quickly during the day

(2) On a cloudy morning

The time when the water body is very oxygen-deficient is in the early morning. The cloudy weather will reduce the photosynthesis of plants. It is necessary to turn on the aerator at this time.

(3) Continuous rainfall should be opened in advance

Continuous rainy days will reduce the photosynthetic efficiency, so it is even more necessary to turn on the aerator in advance. It is recommended that if it encounters continuous rainy days, the machine should be turned on when it is dark to prevent the shrimp from dying due to lack of oxygen. Once a large area of ​​water is deficient in oxygen, the use of oxygenated products can rapidly increase the dissolved oxygen in the water, so as to stop the loss in time.

Currently, there are a variety of oxygenation products on the market. Traditional oxygenated products are limited by technology and formulation. Typically, it takes 3-8 hours to release oxygen intensively. This concentrated oxygen release product quickly releases oxygen in a short time, easily overflows the water body quickly, has poor retention effect in ponds, and is highly irritating to farmed animals. At the same time, the use cost is high, and manual oxygenation needs to be paid attention to from time to time.
