I have had a bad case of food poisoning so no progress on the tank... massman, thanks for the compliments, the lighting is actually pretty tightly arranged to the middle of the tank, I believe there is about 8" around the outside that will get refracted light. finrod2, i made it 36" tall and barely made it thru my sliding door in the back so be careful. Nammy, have you tried your local soft drink companies? The tank dimensions are 48"l x 48" w x 24" tall. The sump is 40"l x 18"w x 18"t.
Hopefully I will be feeling better tommorow and can finally start plumbing.
