Here's the money shots.
I still wanna vent the overflows...about every 5 minutes I get a slight gurgle out of the right overflow...
can't figure out why, must be trapped air, but I can't purge it.
So I'll get an air valve and plumb it to the top of the overflow piping and see if that doesn't do it...
Other than that, it is dead silent.
The QuietOne 3000 is running wide open, and my overflows can keep it wet.
I figure it's doing 3 ft of head and another 2 ft for plumbing so I got to be turning 5-550 gph, and that ought to do her...
