pumps

For a 20 gal. sump set up with a 50 gal. tank, should I get a mag 5, or a mag 7 pump? my head height is 53"...

A MAG 7, it will give you about 460-475 GPH @ 4 ft head height. What is your overflow rated at? That will determine if the MAG 7 will work or not.

Mag 7 will be fine. A Mag9.5 would be fine aswell as long as you sized your overflow to fit the flow fo the pump.

Most likely online but it won't hurt to check and compare. You should decide on which overflow you're going to get the before you buy the pump though, it will make your pump decision a bit easier.
