Good comment specially considering people have tanks without sumps (me included, had a 75g for ~3years) and definitely agree bigger is better. More volume, more stability, plus room for a fuge, frag area etc.

You mention sump doesn't have to be under display, you thinking basement?

No. The tank is in the wall with fishroom behind, so I don't need to have the sump under the tank. I currently have a CPR refugium hanging on the side of the tank. This fuge has been a pain since I keep all sides free of coraline.
