Saltwater and Hardwood floors

[plutoniumJoe]

I had a bit of a problem last night. I woke to the sound of a child pulling tape out of reel quickly every 20 seconds. I couldn't figure out where it was coming from until I saw the jet of air entering my tank. I went to open the sump and felt the water seep into my socks. The return portion of the sumb was almost dry. I installed a Herbie last night, not sure if it is related but my protien skimmer overflowed my ps overflow(1 litre jar). The skimate which was very clear spilled all over the carpet which has hard wood underneath. After trying to clean up as much as I could before my wife woke up. Looking at the floor there is some damage (I am sure not all from last night). The nail holes are blackened and the joints look a bit darker and spread. Is this salvageable and will things continue to deteriorate? What do others do to protect their floors.
