  • 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 pond, etc. we recommend using the Easy Pro AS series Pro-Glass Alumina Air Stones.
  • Barbed inlets have multiple sized barbs, simply cut to fit the size tubing you are using.
  • An excellent choice for pond and water garden aeration since they produce more circulation and water movement.

Do you have a version that would help keep these out of the muck?
Yes, check out the EasyPro DM2, DM4, and DM6 models. They feature a built-in manifold and a polyethylene underlay to keep the diffusers from settling.
