Just kinda trying to get some things figured out here! /site/DesktopModules/NTForums/themes/_default/emoticons/biggrin.gif What would be a good return pump to pump from my basement sump up to the main level where the tank is located. The sump will pretty much be right underneath where the tank will be sitting so we're probably talking like 12' at the most straight up plus the usual fittings and stuff to get it into the tank. Also I plan on having 2 1" bulkheads in the tank to make sure I can deal with plenty of flow if the need arrises. I was kinda thinking going with an external pump to help keep some of the heat out of the tank. Just kinda curious what everyone else is using?
