Pond Boss Forums AERATION Systems questions Diffuser heads

I echo Bills comments. I've seen more "difficulties" with the tube diffusers than with the flat disk type diffusers. As for cleaning them, even the Vertex diffuser disks get growth on them and for optimal efficiency they should be cleaned once a year to keep the bubbles from coalescing. I don't worry about cleaning the diffusers that are for winter use because I want coarser bubbles to create movement on the surface of the pond.

Air stones are the worst for cleaning, about the only way I know is an acid dip to clean them.
