Good deal... let me know how it works out.... be curious of any of my redneck calculations work out for higher flow. Should be close. Sure beats goofing around with U tubes, not to mention forking over big $$$ for the commercial overflows.

I got tired of the the powerhead blowing air bubbles into the display, so I tried moving one down to the sump, worked good for a while, but after a few months it would get plugged up amd have to be replaced. So I switched over to using another one of those Aqualift pumps instead, works like a champ. Now I need to order a couple more to play with.
