ProAir™2 Self-Weighted Air Diffuser by Airmax
Membrane Stick Diffusers
Designed to improve oxygen absorption, the diffuser membranes deliver all of the performance of air stone diffusers without the hassles of replacing cracked stones or frequent cleanings due to debris accumulations. Virtually maintenance-free, membrane diffuser sticks resist clogging and their flexibility eliminates the possibilities of cracking and leaking.
Features:
If you have fish in your pond, always have a backup pump or aerator operating. If your main pump ever fails, having a backup will maintain adequate oxygen levels until you can replace it.
