These EPDM rubber membrane air diffusers are incredibly strong and ideal for pond aeration, circulation, and destratisfying applications. They are an excellent choice for pond and water garden aeration, since they actually produce more circulation and water movement than airstones.
  • Barbed inlets feature multiple size barbs, must be cut to fit
  • Unlike air stones, these diffusers are easy to clean
Usage warning: In testing, these diffusers produce slightly larger air bubbles than airstones, which translates to less oxygen transfer into the water. For fish holding tanks, fish production ponds, and other high fish load applications, use air stones rather than these diffusers.
