EasyPro Rubber Membrane Air Diffuser – 12" – 3/8" – 1/2" barb
These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and destratisfying applications.
Features:
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, etc. 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
