If your gonna keep a reef I would go with a skimmer before a refugium. I think you'd see more of a direct result with it.

The skimmer will remove organics from your tank, mine produces a nasty thick green goo which if you think about it is IN the tank. LOL
The refugium will allow you to grow out some pods and keep macro algae which can help with nitrates.
That's my simple way of looking at it.
