Max sum size for 72 gal Bow Front ????

[beendaredondat]

My skimmer just died, and it's replacement requires a different sump set up than the one I have now. I want to go with a single Aquarium for my sump so now I'm looking for the largest one that I can fit thru the doors while still clearing the back brace of my stand. (cutting the end out, or removing the center brace is not an option). I made a carboard mock-up of a 20 gal (12w x 16H x 24L), and I'm not 100% sure, but it doesn't look like it will clear the back brace as your angling it in. Having my existing sump (two tall rubbermaids joined by a pipe) in the way has made it impossible to tell for sure. I've been trying to find one set up empty in a fish store, but so far no luck. I've even tried contacting All-Glass but no luck so far. Does anyone know of someone out there running a 72 Bow Front with an Aquarium sump in their stand ?????. Any help would be greatly appreciated. Three weeks with no skimmer now.
