How to Use an Oxygenator Correctly

Many farmers have a significant misunderstanding about the level of dissolved oxygen in water. People often assume that aquatic plants and algae can carry out photosynthesis and thereby provide dissolved oxygen. As long as there’s sunlight, they believe the water body will never suffer from oxygen deficiency. Let’s take a closer look below at how to use it correctly. Aerator 。
As we all know, aerators can stir up water layers, helping oxygen from the air dissolve into the water. However, aerators also play an even more critical role in promoting convection between the upper and lower water layers, exchanging oxygen-rich dissolved water from the upper layer with water from the lower layer—and thereby preventing a host of problems caused by excessive hypoxia in the bottom waters.
When is it appropriate to start the aerator? It can be divided into three main time periods.
(1) A sunny noon
On clear days, noon is the period when algae and aquatic plants in water bodies undergo vigorous photosynthesis; therefore, there should be circulation between the upper and lower layers of the water. This not only prevents oxygen depletion in the bottom waters but also helps to avoid the water body from heating up too rapidly during the day.
(2) On a cloudy morning
The water body experiences severe oxygen deficiency in the early morning. On cloudy days, plant photosynthesis is reduced, so it’s important to turn on the aerator at this time.
(3) Continuous rainfall should be opened in advance.
Continuous rainy days can reduce photosynthetic efficiency, so it’s even more important to start the aerator in advance. We recommend turning on the aerator at dusk when encountering consecutive rainy days, to prevent shrimp from suffocating and dying due to oxygen deficiency. Once large-scale oxygen depletion occurs in the water body, promptly use oxygen-boosting products to rapidly increase the dissolved oxygen levels, thereby effectively halting further losses.
Currently, there are various oxygen-releasing products available on the market. Traditional oxygen-releasing products are limited by technological and formulation constraints. Typically, it takes 3 to 8 hours for these products to release oxygen in a concentrated manner. In contrast, high-concentration oxygen-releasing products rapidly release oxygen within a short period, easily causing excessive oxygen levels in the water body. They also tend to linger poorly in ponds and can be highly irritating to cultured aquatic animals. Moreover, these products are costly to use and require frequent manual monitoring and supplemental aeration.
