I do believe that was the owner of the store running out of the way. Originally I was told he was behind the tank, but I don't think he was.
Still haven't heard if insurance is going to cover everything, but I can't imagine that it wouldn't, it's an aquarium store. so they better have breakage insurance coverage! As for it covering a replacement tank in total, that I don't know. I know they have been quoted a replacement tank. I imagine a 1500 gallon custom acrylic tank would be in the neighborhood of $3000-$5000, but that's a total guess.

fill only so no salt either. Don't know if it was just tap water (I'm guessing so) or RO
