How to reinforce floor for a 210g aquarium??

I'm getting a glass 210 tank, 84x24x24in. It will be along the exterior wall of our 1930's farm house. It'll sit perpendicular to the beams. They are 8in by 2in beams, inner spacing between them is 14in and they are 13ft 8in long. There is 1in solid wood flooring covered by 3/4in fancy plywood as the floor. Is there any additional support I should add? If so, how do I do that and with what? Thanks.

Sounds "overs-spanned" already to me but wait for someone to come along with structural framing knowledge.

Not to long ago there was a similar thread here on this same subject, search for that thread and see what information it contains.

On the plus side, it is actually 8 solid inches by 2 solid inches.

I think you are referring to joists, not beams. You need a careful, probably professional, analysis of the capacity of your framing, or you run the risk of having the aquarium fall through the floor. To do the analysis, you need the exact (not nominal) dimensions of the joists, the clear span of the joists, the species and grade of floor joists, the exact location of the aquarium with respect to the joists, and the total weight of the aquarium. A 210 gallon aquarium is likely close to 2000 lbs, which is a heavy point load.

Be careful on this one, the consequences of a mistake could be fatal.
