Water coming out of the tank makes loud noise...
I just setup 90 gal with overflow box. The water that is coming out of the tank via Durso standpipe makes loud noise when it's entering the sump. It looks and sounds like water is boiling (lots of big bubbles).
The out line from the tank is 1" and inline is 3/4". Durso pipe has a hole on top and this is where air gets sucked in.
What do I do?
