Not sure if this is the right place for this question, but I'll ask anyway. I want to upgrade my aquarium but I'm not sure my floor is strong enough. The aquarium would be about 5x2x2 feet, and the total weight would be around 1400Ib's. I live in a first floor flat, built in the 70's, with a concrete floor. The aquarium would be against an outer wall. Any advice would be greatly appreciated Nev
