Rubber Membrane Air Diffuser
These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and destratisfying applications
- Unlike air stones these diffusers are easy to clean
- In testing they produce a slightly larger air bubble than air stones which translates into less oxygen transfer into the water, so for fish holding tanks, raceways, fish production ponds, we recommend air stones
- Barbed inlets have multiple size barbs, simply cut to fit the size tubing you are using
- An excellent choice for pond and water garden aeration since they actually produce more circulation and water movement
- New 6" weighted diffuser available, part #RAD650W
