Here's a lousy pic. of the type of refugium I've been making from old aquariums. The last one I built was out of a 20 long. My next one will be out of a 50 long. Be sure you build the sump/refugium out of a tank large enough to give you a big safety margin (i.e. lots of gallons between the pumps running dry and the sump overflowing during power outages)... my 20L, for example, allows for ~5-8 gallons of error.
The main idea here is to build a middle chamber without too much turbulance. The water should really flow over the top, without disturbing the live sand and macro at the bottom. With this design, you can fill the sump almost to the brim without disturbung the live sand. *note: you'll not want to fill the sump to the top, as it will flood, during a power outage.
Also, I forgot to add a light in the graphic... the light gfoes, of course, on the top of the refugium. Most people report that poor, cheap NO lighting works best. My 20L refugium has 2 9W PCs and the Macro is thriving.
Enjoy
