will a 150 gallon need a re-enforced floor?

[targa81]

My 155 is on the second floor and I too was concerned about whether the floor needs reinforcing. From what I understand, 150 gallons is about where one starts getting concerned. I do know you are better off against a load bearing outside wall than as a room divider though. To be totally sure you'd best get an engineer to test the load capacity or just do as I did and fill it up. Any others with big tanks on the second floor??
