This is the thread on my pond with some of my experience with aeration. Kind of long and probably boring. But I started out with multiple diaphragm type pumps and eventually went to a vane type pump.

You will need a separate line to each diffuser with a valve block so you can balance the flow to each diffuser. Like Bill Cody says. Different depths require different pressures to even the flows out between diffusers.
