What type of powerhead is recommended in a 20 gal long tank?

I guess it is all depends on what kind of corals you wish to keep. Generally speaking 10x is a minumum water flow you want: 200gph. However, you might want to consider 2,3, or more smaller powerheads placed strategically in your tank so there will be no dead spots and to create a bit turbulent flow instead of laminar provided by only 1 power head.
Every tank is different, so it is hard to say where and how many powerheads you need. You'd have to experiment a bit until you reach desirable flow.
