i want to put a 150 gallon 4ft wide tank on a full stand (not metal 4 prong) on the 2nd floor of my house. It will be built into a double door closet that i am going to convert. I plan to put a 3/4 inch wood board on the floor under the tank for proper disbursement. do you think it will be a problem>? It would seem that the weight per square inch should be that bad. my bed sits on 4 prongs and holds a heavy mattress and boxspring along with 325lbs of people on it nightly. WOuld seem that is more of a weight problem cuz it only touches in 4 places? Please advise...
