Floor reenforcment

[Holyreefer]

So im moving AGAIN! And i have a 210 tank that will be seating on the oringinal stand it comes with. The location im moving to is the 1st floor duplex. Its hardwood floors but the location i would like for my tank to be seat right where the main support for the house is. Heres a pic.

Do i need to add additional support?

the cold air return is the back wall of the tank.
Please any insight would be great don't want this tank going through the floor.
