Trying to pick the right return pump

[xblade]

Thnx for all the input guys...I'm thinking, go big.
I'll shoot for about 800 gph at 5 foot head.
What pumps would you recomend?(in the $200 or less catagory)

Should be getting tank back soon.And then the fun starts.

When estimating head pressure you should multiply the vertical height by at least 1.5 to take friction and minnor losses into consideration. A factor of 2 is typically what I go with because over time the pipes become dirty and rough which adds significant friction.

So if you have 4 feet from sump level to display level you should estimate 6-8 feet of head pressure.
