This is getting very tough for me to figure out.
I started with the 1/16th...then I tried the 5/64th...then 3/32nd...then 7/64th...then 1/8th. This can't be right.....Durso's site says that 1/16th should be all you need. I doubt I'm pushing more then 1000-1200 GPH through this thing.
My Durso is 1 1/4 pipe with a 1" bulkhead; and my return line in my sump is NOT even submerged. Did the same thing when it was submerged too, however.
Anyway...I'm trying to get an idea how large everyone made their air holes in their Durso Standpipes.
Thanks,
