Description
Rubber membrane air diffusers are incredibly strong. Ideal for pond aeration, circulation, and destratifying applications.
These diffusers are an excellent alternative to air stones because they 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
