Protecting fishroom floor?

[coloradoreef]

I'm designing a fishroom in my new place. (watch out for a build thread later) The house has hardwood floors, and I'm worried about damaging the floor with saltwater. I though about putting some cheap vinyl/linoleum down, but I'd like to avoid ruining the hardwood with an adhesive. This is a 10'x12' bedroom.

I've considered putting floating vinyl down, but that seems expensive, and I've also thought about just putting black plastic on the floor with some cinder-blocks in the corners, but I think it would be difficult to deal with.

Thoughts? What have you folks done to protect your floors from saltwater?

have you thought about pond liner? basically, 45mil EPDM(rubber membrane), works great for ponds and hydroponic applications. its thick, tough, comes in many sizes, easy to install, remove and take with ya and its pretty affordable.

this is more that you would need:

That's what I used underneath the rug that my tank sits on. Easy and no damage so far.

I have a deck on the back of my house with a finished room underneath. I covered the deck with roofing EDPM (less expensive than pond liner for some reason). The corners were folded so water could not escape and then glued down. You could do something similar if you buy the EDPM 6 to 12 inches bigger than the room. You could fold and glue the corners with out gluing anything to the walls or carpet. I don't know what you would do at the door to the room.
