Hi I'm planning on getting a 300gl tank but I live on a Back house the floor is cemented but not sure if the flooring will be strong enough to carry the weight of the tank and the top part of the cemented floor is laminated wood will the weigh of the tank crack the base cement? will it crack the laminated flooring I have several tanks right now the biggest is a 120gl but having second thoughts on the 300 any opinions will be greatley appreciated Thank's in advance.
