Hey I'm in the process of adding a sump to my 55 gal tank and I was just wondering what size or how many GHP of a pump I would need to pump the water from my sump back to my tank? The it will need to pump around 3 feet back up to the tank and my overflow box is rated at 600 GPH. Thanks

Maybe..depends on the "big picture" for flow in the tank..
What is the total "Goal Flow" for the tank (10x 15x 20x 25x more....?)
Do you want all of the flow to come from sump return or do you plan on using supplemental powerheads or closed loop system for additional coverage and/or current switching devises...?

I already how 2 powerheads in the tank I just want to know about an equal for the amount of water heading to the sump. Do you recommend more or less GPH than your overflow box?(I'd imagine close to it so your sump won't get to much or little water) Would a water pump from Home Depot work or would it be better to go somewere else?

If you are using supplemental circulation...good...
To "match" your overflow (600gph) you will want a pump that will deliver "just slightly" less thea you oveflow can take out...
At 3' head and 3/4" returmn line with 3- 90* elbows to get into tank...(standard calc assumptions)
The "external" Iwaki 30 will return 495 gph...
A "submersable" Mag 7 will deliver 454 gph...
At same head and larger return line 1"...(better choice)
The Iwaki will deliver 515 gph...
And the Mag 499...
All "safe" numbers for a 600gph overflow...
You could "push" that a little bit, but at that point you will want exact measurements on head height and pipe and outlet layout to do calcs...

And probably not "Salt water" Proof...metal parts etc...
