WTB external pump

[cmpenney]

I currently use a Gen-X PCX40 to ump water from the basement to my display tank. I'm looking for a pump that I can use as a backup. It needs to be as efficient as the current pump and move at least as much water and be external. Anyone have anything that will fit the bill?

I have a few Reeflo that may fit your bill...
