Recommendations for pump size?

[The Gipper]

I'm setting up a 120 gallon (48x24x24) heavily planted (CO2, 2.9 watt/gallon, etc). Wild angelfish will be featured fish.

I'm going to use a wet-dry, but am not sure about the size of the pump I need (gallons/hour). I will be using a spraybar as return.

Obviously I need water movement, but I don't think strong currents are advisable (or does it matter?)

Any suggestions here?

If you are having live plants....I think you should have the water changed around 6 times per hour. So, that means for 120 gallons you would need something that would move 720 gallons in one hour. Go to http://www.drsfostersmith.com/product/shop.cfm?siteid=6
and look under water movement equipment. They have a variety of pumps to suit your needs.
