Good evening... Thanks for the tips on the video...
I'm using an Airmax system (PS10) with one diffuser (4 membranes). Where I have it is about 22-25'. My neighbor's PS10 is about 30' deep and not near as much of a boil.

At times I wish it wasn't so much... With the pond being less than a year old, I'm still skimming all of the sediment, along with all of the runoff from 18" of rain this summer. The aerator is foaming up the sediment...along with the waterfall...
Thanks for stopping by.
