The aerator is a fishing machine for fish farming, it can be said that there is no aerator without fish. However, some people only turn on the aerator to increase oxygen when the fish is floating, and simply use the aerator as a "lifesaver." In fact, the aerator should not be used as a "life-saving machine", but as a "production-increasing machine".

Why do you say that? You have to know that the abnormality of many indicators in the water is actually caused by insufficient oxygen. Why does the sub-salt exceed the standard? Excessive ammonia nitrogen? Excessive hydrogen sulfide? This is because the dissolved oxygen in the water is insufficient, and the residual bait, feces, and algae carcasses in the pond will be decomposed into these harmful substances. Before the fish floated, these harmful substances were already being produced. If you just use the aerator as a "life-saving machine", sooner or later, harmful substances will exceed the standard. At this time, turning on the aerator will not be of much use.
