I have the tank all setup skimmer and all the other equipment. But one question I have a mag water pump and it really doesn't pump the water very well. What pump would you recommend. I think I have the mag 3.

how many gallons per hour are you looking to get? What is the head height you are working with? What size are the drain and return lines?

I would like about 4 to 5 hundred an hour or more. The Drain and return are 1 1/2 in , head height no more then 4ft.

Not sure of the full plumbing layout (90 degree bends and such will restrict flow) but at 5' of head a mag 7 would give you 420gph and a mag 9.5 would give you 750gph.
