1. Look at safety
When purchasing, be sure to try it and check whether the casing is damaged, whether the threads have fallen off, and whether there is any leakage of electricity or air.
2. Look at performance
Look at the oxygenation effect of the aerator, especially whether there is a significant difference in the speed between the fast gear and the slow gear. The one with the larger difference is better. Choose an aerator with low noise and large air output. Too much noise will have adverse effects on aquatic products, and a small air output may not meet the requirements.
3. Check the manufacturer
Choose products produced by regular manufacturers. Especially when purchasing a large aerator, you must look at the manufacturer’s certificate, otherwise the quality will be difficult to guarantee.
4. Select the type
(1) The impeller-type aerator has good power effect and large working area, making it suitable for raising domestic fish.
(2) The water wheel type aerator also has very good power effect, strong push flow effect, obvious oxygenation on the surface of the water body, and is suitable for shrimps and crabs.
(3) Swing-type and jet-type aerators are suitable for deep-water aquaculture and long ponds.
(4) The water spray aerator can aerate small ponds and is suitable for small fish ponds in garden-style tourist areas.
(5) The deeper the water of the inflatable aerator, the better the effect. It can dissolve oxygen gently up and down the water body without damaging the bodies of fish and shrimp. It is suitable for oxygenating fish and shrimp ponds.
