This all makes a lot of sense. Thanks for the summary.
The Vertex diffusers are rated at .5cfm to 2cfm. If I was trying to run one of those with my compressor which puts out 4.5cfm that would probably be what caused my pressure at the pump to go up.
I am wondering if I may not need to bleed some air off or at least run both diffusers even though not needed for the size of pond I have.
Any harm in running both? Can you turn the pond over to much? Doesn't seem like it would be an issue.
I am hoping to create some good water for the family to swim in as well as restock with bluegills so my 2 and 4 yr old can have some fun catching fish in the future.
I built a manifold tonight that I can hook up when it's nice again. It will allow me to have both diffusers plus a line to bleed off air if needed.
Thanks again everyone for getting me headed in the right direction.
