Air Diffuser
Disc Station
Diffused aeration provides low-cost effective aeration. This type of system is most effective in ponds. The compressor is connected via polyethylene tubing to diffusers that are placed on the pond bottom . When the air is injected to the bottom of the pond millions of tiny bubbles rise to the surface adding oxygen and circulation to the complete water column.
The plastic box is hollow design which can sand or little stone to weight it. It is easy to maintain and
