Thanks, what counts as an obstruction by rockwork? Within 6" or some such?
Basically, I'm planning a 66x60x18 310g system, viewable from 3 sides. I would like to put the wavebox dead center in the back panel. Does this mean I wouldn't be able to have any rockwork in the center of the tank?
Also, can you tell just from the dimensions what size wave I'd get in this tank? I really would prefer no more than 1-1.5 inches.
