Aquaculture is inseparable from aerators, but many users often use them incorrectly during use, which can result in poor aerators and even the opposite effect.
Proper use of the fish pond aerator can not only greatly reduce the cost of aerators, but also effectively improve the quality of the fish ponds, reduce or prevent the occurrence of fish diseases, and increase the profit of farming.
The sun is abundant on sunny days, the photosynthesis of phytoplankton is strong, the dissolved oxygen in the water reaches saturation, and the lower layer consumes more oxygen factor, which is easy to generate oxygen debt. However, due to the influence of thermal resistance, it cannot be convected in time. At this time, it is turned on at noon. The role of timely delivery of saturated oxygen in the upper layer of water to the lower layer to improve the dissolved oxygen conditions of the lower layer of water.
The next morning on cloudy and rainy days: On cloudy and rainy days, the photosynthesis of phytoplankton is not strong, and there is less oxygen. The dissolved oxygen conditions in the pool water are relatively poor, which is easy to cause floating head. At this time, it should be turned on very early. The floating head was opened before: When the pond was patrolled, it was found that the fish had a floating head and should be turned on in time. It is open in the middle of the night when it is rainy and rainy: in the rainy weather, the dissolved oxygen in the pool is extremely poor. It should be turned on early to prevent floating heads. It is not turned on in the evening on a sunny day: At this time, it is easy to cause the upper and lower layers of water to convect in advance, which is easy to cause floating head. Do not turn on before the thunderstorm in the evening: At this time, it is easy to cause the upper and lower layers of water to convect in advance, resulting in an acute floating head of fish. No raining at noon: At this time, the opportunity to reduce the photosynthetic oxygen production of the upper phytoplankton and accelerate the consumption of oxygen.
