If you plan on running all of the overflow water through your skimmer your pump will need to be matched to that flow.

Unfortunately not an easy answer without knowing what equipment you would be using and what sort of pluming will be used. I usually pick a return pump based on the number of devices I plan on running off of the one pump (skimmer + phosphate + UV + head loss etc...) = the overflow rate desired. Circulation within the tank is better attained using power heads, wave makers, closed loop...etc

Keep in mind that if your flow is too high you can always bypass back into the sump, however inefficient, but if it is too low you will need to upgrade or add additional pumps.

All that being said have a look @ these Eheim 1262, Danner Mag-Drive Supreme 9.5

Adam,
My preference if I had to use a hang on overflow would only be a LifeReef. I would use no other myself. Of course drilling is by far the best way to go.

I have a 35g with a 25g sump and run an Ocean Runner 2500. If you wished more turn over, not really needed though, one could go to the next size. Great pumps at a decent price.

As for skimmers, I,m running a SWC 160 cone. Excellent skimmer for the price. Reviews on them in the equipment forum. Also many other great in sump skimmers, from some of our sponsors. Perhaps scan some of the journal threads or again, in the filter section of the equipment forum.
