I sure this has been asked a lot but....
I have just started my tank after months of setting up. My tank came from Glass Cages with an internal overflow with 2 predrilled holes, one is for a 1" and the other is an 1 1/4" bulkheads. The water is just falling through the standpipe into my sump dragging all sorts of air with it. My standpipe is 1 1/4" reduced to 1" (i reduced the size of the 1 1/4" bulkhead to 1") and my plumbing is 1" from the bulkhead to my sump. I do have a hole drilled in the cap of the standpipe with a small piece of silicone air tubing. If i pinch this closed or even half closed it pulls a full siphon.
Tank is 120g. My sump is a Trigger systems 26. Mt return pump is a Jabao 6000.(running on low speed, for now)
It sound like Niagra falls.
Did I miss something or not understand something?
Any help would be greatly appreciated.
