will a 150 gallon need a re-enforced floor?

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

Ok, I am doing a little math to figure out I am not that good at Math btw) so let's see if this makes sense

According to this http://www.tpic.ca/3_specified_loads.pdf, our home floor live load is 1.9 Kpa which is around 40 pounds per square foot.

Your tank is 72x20 so roughly 12 sq ft in total.
Now calculate how many pounds of your tank:
a full water of 150 gallon is approx 1224 lbs
+ 280 lbs (sum) + 100 lbs (stand + equipment)
so that is around 1604 lbs

so 1604 lbs over 12 sqft is 133 lbs per sqft. So you are 83 lbs over per sqft

I am probably wrong here lol

I read that article too before I got started on the 150 and it just made my head spin.. and I didn't bother doing the math. I just put a 150g aquarium in my living room and that was that.
