My 200gal is 48W x 30"D x 30"H...it's a 150 tall, only 30" deep, instead of 24".
It's a pain the rear, to pick up stuff from the bottom of the tank. Especially if you have aggressive fish. Nothing like throwing your whole arm, up to your shoulder/neck, trying to retrieve something from the bottom, while trying to fend off large, biting fish. lol
