Given the space I have available, the best option seems to be to place the refugium right next to my sump.  My plan is to set up a small pump to pump from my sump into the refugium with an overflow back to the sump. 
 
How does that sound?

 Is it possible in your plan to place the refugium higher than the display tank?
