Snrub, THANK YOU AGAIN FOR YOUR GUIDANCE ON RIGGING UP THE DIFFUSER! It sinks and works perfectly. Man, this setup is so cool!
To avoid potential problems in the air hose, one very important question I have is: With my 5/8" weighted hose from pump to diffuser (Matala 9" rubber membrane single mount), do I need to have a check valve in that line? If yes, I'll pull up the diffuser to put one in at that end.
Thanks again! I'll include some photos and links to my videos of it as soon as I put in a check valve if I need to.
