Do you already have the tank/stand? or is it something you are looking at buying?

All ready have the stand that I built, and have the tank already..its the old style 45 tall from all glass aquariums (i think it was discontinued, and redesigned) not bad for 50 dollars, though.

So the sump would just be like another aquarium under the primary one?
