Totally agree.
My tank crash when somebody turn off my Generator after a hurricane. I had a friend come over right after the hurricane to make sure everything running smoothly, and it was. Then somebody turn off the generator by shut off my natural gas line, within 24 hrs of me coming home. The tank was crashing as I got home. 400 gal total volume, I cannot do much about it but able to save most of my anemones by removing them and send them to a friend's tank. Fish and SPD was a total loss, few LPS survived. My 24+ inches Gigas was irreplaceable.
I actually remember reading that. It's why I have a sign over the emergency shutoff next to my generator to only close if there is an observable gas leak.
