Suggestions for a tank "skirt"

I am moving next week and was hoping someone might have a suggestion to combat water damage to the floor beneath the tank.

I have a pentagon acrylic tank and acrylic stand and in my current house the salt creep damaged the wood flooring around the tank perimeter.

I was thinking of something like the rubber mats that are sometimes used under clothes washers, but since its a pentagon shape its a little more difficult.

Any suggestions?


Thanks.
