Maintenance is a much bigger pain when you get wet up to your armpit vs. elbowI almost got a 30” deep tank but tried to get my arm down to the bottom at the store and couldn’t. I ended up getting a 24” deep tank instead.
I would consider a deeper tank in the future if I had a fish only tank where I didn’t need to reach the bottom so often, but 36 I think would be my max height.
My length and width would be determined by how much weight my floor can hold and room size (and bank account). Width would also increase if I set it up as a peninsula and could get to center from both sides.
Until I got to the bottom I was going to say door frames can be removed along with the side of a wallMy door frames are only 30” wide, so I’m limited to 28” in either height or width. I just requested some quotes for a 30x30x27 with a 28” tall stand. My 180 (60x30x24) sits on a 28” stand for this very reason, otherwise I’d have done 60x30x30 with a 32-36” stand.
Short story long, 30” would be my max if I wasn’t limited by my door. I have no max on width or length
