Don't know if you remember me, but I was trying to pull together plans for a pond build. Have looked at other options, and this is probably what I am going with. Could I use this as a fluid bed instead of a settlement chamber? If so, would it be drilled differently? Still have the stand pipe? Could I use a 9 inch air stone, or do I still need to do a air diffuser/manifold with grates for the bottom?
The definition of insanity is doing the same thing and expecting different results.
