Difference between hydroponics machine and aerator

The difference between hydroponics machine and aerator, the advantages of hydroponics machine: generally, it is used in tangkou when electricity is difficult and there is acute floating head. Chemical aerator is used to reduce stress, improve drug effect and achieve rapid aeration effect. According to clinical experience, chemical oxygen mixture can be sprinkled when using fish medicines such as pesticides, which is beneficial to the rejuvenation of aquatic animals such as fish, shrimp and crab.

2. Disadvantages: (1) requires a large amount of labor and high cost. The floating head, which can only be used to rescue fish, needs to be equipped frequently during the breeding period, but it is easy to reduce the effect because of improper placement.

⑵ It is not suitable to be used in ponds for breeding fry to prevent bubble disease.

⑶ Excessive use of chemical oxygenator is easy to cause harm to fish, shrimp and crab. 2. Advantages and disadvantages of mechanical oxygenation. Advantages: (1) The water pump aerates the aquaculture water by adding water at the same time, which has multiple effects. ⑵ The aerator not only increases oxygen, but also has the functions of stirring water and aeration, which promotes the reproduction and growth of plankton and improves the primary productivity of the pond. ⑶ Compared with the traditional impeller aerator and waterwheel aerator, microtubule aerator has the effects of uniform aeration at multiple points, safety, energy saving and water saving.
