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??

ya, that was my big concern, the fact that it is a room divider. What it has going for it though is the fact that it is really close to the main support beam, almost like it is up against a wall but not quite as strong I suppose. Also, it runs perpendicular to a bunch of beams, as opposed to if it was up against the wall where it would run parallel to only a couple of beam probably.

You should not have a problem if you run perpendicular to the floor joists and close to main beam that support the joists. I have a 150gal. DT and 50gal. sump under the stand. Dim. of stand is 48" x 30" with a soild base (plywood) which sitting on 4 floor joists 2 x 10. Before I started to fill it I had a plumb bob hanging from the joists in the basement so I can check if the floor was bending due to the weight of the tank. It"s been over a year now with no problems.
Hopes this helps.
