Definitely good information, although I wish the system had the pressure gauge and maybe more specific to my needs (1.5). The deepest diffuser valve is all the way open. It looks like the one in the shallower area is partially closed.
I will inquire about the requirements for this unit and I understand the shortening of life by closing off valves and creating back pressure.
What if I only went with one diffuser, leaving the second one to bleed off the air? Would one diffuser be enough for the pond? The diffusers are single membrane units.
