Hmm the damaged caused to landlord property is probably way way less than the tank/equipment/corals//fish to replace if something happened don't worry about it. Wood floors would be fine after they dried out, assuming once off accident not a regular occurence.
A reef tank of that size is $5000 or more, carpeting a room is what $500.
