If you have a grossly over-sized skimmer then increasing the flow through the sump could possibly achieve a bit heavier skimming, but that would be negligible.

Powerheads are for provide flow for the corals and preventing detritus settling. For SPS corals you're looking in the 50-100x turnover range where LPS and softies are happy with 10-25x turnover.
Very well put Mindy. Maybe decide on your skimmer first and then look at the return pump.
