Picked up used tank/stand. Advice needed

[GaCichlid]

So, I picked up a 72 gallon bow front drilled tank I was gonna use for salt water. Came with all the parts, sump, pump, heaters, lights, etc. On the base of the stand it seems like the guy had let a ton of water either dripping out or evaporation from the sump just flow. It does not any structural damage on the side of the stand, it is just the bottom that does not look to hot. I was thinking of taking the base off and just putting a piece of plywood as a new base. Or could I just leave the original swollen mdf there and just put another sheep of plywood under it? Keep in mind I am in an apartment so the tools are sort of limited to what I can do. Thanks everyone.
Gonna try and upload pictures from my phone. Cannot add them from my laptop

Hard to say without seeing it, but I would probably just fasten another piece of plywood to the bottom, if I Could be sure to put the fasteners in undamaged wood (like the sides)
TAking out the old MDF would probably look better. Not sure how important looks are to you.

A pic would sure help. If it is just swollen in the middle of a flat price I can't imagine it is hurting anything. May be able to sand the swell out of it and paint it.
