ok so i bought a 200 gallon with wood stand and top for 300 bucks which is a steal! i live on the bottom floor of my condo BUT its not cement under just a ton of wood beams. i know the tank will weigh about 2000 pounds with water and rocks in it. i its 6 feet long and 2 feet wide so i think it would distribute the weight pretty well and i might even put a piece of plywood under it to distribute it even more. yes i read other posts about apartments but didn't get the answer i was looking for. thanks ahead of time. i might ask the homeowners association if i can have a water bed
