1. Turn on the machine in the afternoon (2:00~4:00) on a sunny day. At this time, turn on the jet-type aerator, so that the dissolved oxygen produced by the photosynthesis of the surface algae can be transported to the bottom of the pond in time, which can effectively reduce the "oxygen" in the pond. debt” and temperature differences. the
2. Turn on the machine on a cloudy day. At this time, the photosynthesis of algae in the fish pond is weak, and the dissolved oxygen condition is poor. Turning on the aerator can alleviate the lack of oxygen in the water body and reduce the chances of enteritis and gill rot in fish.
3. Turn on the machine in the middle of the night in continuous rainy days to prevent hypoxia and flooding of the farmed fish.
4. When spraying drugs (especially insecticides and disinfectants), turn on the machine so that the drugs can be evenly distributed in the pool as soon as possible, which can avoid the damage of drugs to water quality and the occurrence of instant poisoning of fish. The aerator should also be turned on when fertilizing and using live bacteria preparations, so after using such products, a large amount of dissolved oxygen in the water body will be consumed.
5. If you do not turn on the machine when the sun sets in the evening, the photosynthesis of the algae in the pond will stop, and it will no longer be able to supply oxygen to the water. If it is turned on at this time, the dissolved oxygen in the water body will be reduced, and "fish floating head" will be more likely to appear in the early morning of the next day.
6. Do not turn on the machine during heavy rains, because heavy rains are often accompanied by strong cooling, which can easily cause "density flow" of water bodies (due to the low temperature and high density of rainwater, convection occurs in pond water, resulting in the emergence of poor dissolved oxygen and a large amount of organic matter at the bottom. )” causes the water body to be rapidly deprived of oxygen. In mild cases, the water becomes muddy, “algae-repelled”, blackened, and reddened, and in severe cases, the ponds are flooded due to hypoxia. If it is turned on at this time, it will accelerate the occurrence of this process.
In addition, the start-up time should be longer in hot weather and shorter in cool weather; the start-up time should be longer in the middle of the night and shorter at noon; Time is short.
