AIO 80g Floor support needed?

[Turnage]

So I have an Inovative Marine AIO 80g arriving soon and the chosen location for the tank is in the middle of a 30' X 30' room. It's a single story house built in the mid 70's. I haven't gone underneath the house yet (back injury ATM) to see if the floor joist are 2"x10" or 2"x12". Am I safe to place the tank as is or should I put some floor jack in?

Tank length is 48"

Edit: found a great sticky thread on this subject. I think it has answered my question.

Glad you were able to find the answer!
