You and I both have the same brand of diffusers so with that in mind I set mine 27" off bottom plus the diffuser base. That eliminated the disturbance of the bottom clays. I set mine in 10' and 12' water depths but as u know they are shallower in the summer due to pond dropping during the Texas heat. Like 8 and 10'. I made several attempts in trying to stop stirring up the bottom clays but I only had success where they are at now. I built my platforms/tables out of rebar and they work great and cheap to build


Do not judge me by the politicians in my City, State or Federal Government.
