Pond aquaculture is inseparable from dissolved oxygen in water. When dissolved oxygen in water is high, aquaculture is relatively simple. To improve the dissolved oxygen in water, you can increase oxygen by drugs, photosynthesis of aquatic plants, or mechanical oxygen. Now speaking of mechanical oxygenation, the more commonly used is to use the three leaf roots blower to oxygenate the air through the air, directly inject the air into the water body, and improve the flow of the water body to increase dissolved oxygen. Self sinking tube is an important part of bottom oxygenation.

Self sinking tube is also called self sinking type oxygen increasing tube, which can be used as ventilation hose or intermittent point oxygen increasing. Specification: 14 type self sinking pipe. The outer diameter is 14mm and the inner diameter is 9mm.
