We have an AGA 210. it is only 29" At that depth with 3" aragonite I am up to the armpit whenever I need to get to the bottom in an emergency.
Ours has the megaflow weirs and they work great at keeping the WC clear. They are not in the corners so you see no plumbing from the sides but do protrude 4 inches or so into the tanks footprint.
Aqueon makes it now as they matured from AGA, pretty sure you can get these at a LFS nearby.
