will a 150 gallon need a re-enforced floor?

Ya, I thought that was odd too, but for some reason they are measuring 2x9s :-) could be my tape measure or my lack of measuring ability.. but putting one end of the tape measure at one end of the beam, and dragging the tape measure to the length/width/height (whatever dimension you want to consider it), the tape measure reads 9 inches. *shrug*

A 2x10 will actually measure 1 1/2" x 9 1/4" so it sounds like thats what you have.

All lumber is measured Pre-Planed. That means, when it comes out of the sawmill, it's 2x4 or 2x10" rough cut. When it goes through the planer, to make the boards smooth, this removes some wood, thus a 2x4 is acctually 1.5"x3.5" approx.
Heres a link to a chart
