Hobart,

I am curious. You say you are running 3 diffusers and you balance them by watching the bubbles on the surface? Are they all pretty much at the same depth or do you have one in a lot deeper water than the others? If yes, does it seem the shallow ones bust more? If yes, then you might want to think about restrictors on the shallow water diffusers as Snrub mentioned. I am not a pro, IMHO you should present your problem to someone that is.
