This innovative diffuser maximizes circulation and oxygen transfer with an extruded EPDM tube for tremendous longevity. Bubble sizes that decrease as pressure rises maximize surface area for extremely efficient gas diffusion. Aeration diffusers accommodate nearly every depth and profile. Diffusers can be filled with gravel or sand to keep weighted to the bottom of the pond.
Includes 3/4" check valve, 3/8" insert fitting, strain relief
Produces ultra-fine bubbles with little back-pressure
Unique diffuser shape accelerates rising water column
