Thanks for the picture Keith. I wish i took a snapshot of mine, but your 'muck' on the diffuser looks more sticky, more tenacious. Mine was much hit and miss chunks, yours looks like glue all over the diffuser.
I haven't checked my air filter and will do that as I take the aerator off line this fall. I checked this spring and after 2 summers of use the air filter looked brand new yet. I have lots of pollen in the air and the water so not sure how the air filter stays clean.
if anyone wants to see another nice way to snag the diffusers from the bottom and be sure they settle back down straight when you are done esshup shared some of his experience. He has experience in this area and can offer some advice. Shoot him a PM.
