will a 150 gallon need a re-enforced floor?

I agree with what everyone else has said too, and also would like to point out your stand has alot to do with it, if you have a stand that is totally flat on the bottom, eg, a piece of plywood, the weight is distributed more equally across the full area, unlike a stand with just rails or independent legs.

here is a very long artical about floors and load distribution.
