I think it's really what you like and are willing to deal with. I noticed with my 300gal at 31in tall was still a pain because when it came to doing anything in the bottom it was a task, but when everyting was in place and clean the shear look of all front, especially when you fish are larger, looks impressive. Can;t wait to get a larger 900gal with a 44 to 48 tall foot print. Pain and Pleasure..
