Ok this may sound like a silly question,Im thinking on upgrading to a 150 gal tank,and I was wondering with this size tank will I have to do any re inforcing of the floor joists,it will be on the first floor and will of course be a reef tank.I currently have a 90 and it has been ok for the last 6 yrs.A fast reply would be a BIG help considering that Im going to check out this tank (and hoping to buy) tomm....thanks
