Rubber Membrane Air Diffusers
These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation, and destratifying applications. Unlike airstones these diffusers are easy to clean, EPDM membrane cleans much better than porous air stones. In testing these diffusers produce a slightly larger air bubble than silica air stones.
