So I am wanting to upgrade my 55G to a 120G tank.... I feel like I have already outgrown my 55G. The question I have is about the weight of the tank. I live in a newer home that is a one story house. Will a 120G tank be too heavy for the flooring, or should I be ok? Right now my 55G with a 30G sump has been fine. But I am not sure if a 120 w a 55G sump and maybe even a 30G Refugium might be too much weight.
