My experience has shown in a reef aquarium, always go as big as you can. Adding a refugium will give you more water volume. This will help aid in water stability. Thus help is some fashion the amount of water changes needed. It will help keep all parameters of the water stable. IE temperature, salinity, minerals and trace elements.
It will as previously mentioned allow a place to grow macro algae to help remove nitrates or just to feed to your fish. It will allow a place for copepods or rotifers to grow and breed without being completely consumed by the livestock in your tank. (Thus the hapless few that get caught in the water stream are continuously feeding my tank.)
I would also recommend as large a protein skimmer as you can afford. This will help keep nitrates down,...and you never know when a good deal pops up on a larger tank.
+1 I plan for the absolutley largest fuge I can fit under a DT. Also I partition mine for specifc purposes. Keeping an area to cater to the specific needs of sponges, tunicates, and squirts can do more for the overall stability of a system than most people realize. The tough part is there's no real metrics for this, no calculator, no formula. Just as big as you can get it, and as diverse as you can imagine.
+1 on what fun a fuge can be to watch. Amazing organisms in there for sure.
