Powerhead advice

[Scotty87]

I'm kinda new to this and this is my first post. I currently have a 20g tall and in the process of building a 72 gallon bow front. How big of a pump do I need in my sump( it's a wet/dry system) and how many and how powerful of power heads do I need. I will be having a reef tank with peaceful fish once done. Any help I greatly appreciated.

Is it a drilled tank or have an overflow box?
