EPDM fine bubble diffusers are an excellent choice for aeration in ponds and tanks. These EPDM diffusers are very durable and strong and very easy to clean.

Available with 1/4" - 3/8" barbed hose inlets or 1/2" MPT. These aeration diffusers are not self weighting and must be secured or weighed down to keep from floating in ponds or tanks.

  • 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 using our fine bubble alumina air stones.
  • An excellent choice for pond and water garden aeration since they actually produce more circulation and water movement.
  • Also can be used in wastewater aeration and tank mixing
