Rubber Membrane Diffuser - 6" Long - 1/2" MPT - RAD650

Rubber Membrane Diffuser - 6" Long - 1/2" MPT - RAD650

Product Details


These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and destratisfyingapplications. Unlike cheap air stones, these diffusers are easy to clean. EPDM membrane cleans much better and easier than the porous air stones.These diffusers are an excellent choice for pond and water garden aeration since they actually produce more circulation and water movement.

In testing; these air diffusers produce a slightly larger air bubble than the air stones, which translates into less oxygen transfer into thewater. So for fish holding tanks, raceways, fish productions ponds, etc. we recommend usingalumina air stones.
