Placing a Tank on the 2nd Floor

[WarDog]

I work on these homes all the time. 125 gallon tank is going to weigh 1500lbs with extra goodies. No problem at all. If in doubt, gather 8 grown men and stand them on the spot in question. Betcha the floor doesn't collapse.

It's not so much the floor collapsing that I'm concerned about, more the floor/tank shifting and popping a seam or cracking.
