Well if it makes you feel better, I learned the hard way also (a couple times). I had an 85 gallon tank with moray eels and it had a hose failure. It put 40+ gallons of salt water onto the floor which was carpet over hardwood. By the time we came home that day, it was too late. The flooring under the carpet had buckled about an inch and I found my self replacing a room full of flooring. I also had a 55 gallon tank that the whole front panel popped off of. I was standing right there as 55 gallons hit the floor in an explosion. What a mess!!! Cheers!
