bah, you think thats bad. I had nearly 400 gallons on my second story. LOL However, I checked prior on what would support it below and had walls and a closet, so it was every bit as strong as it would of been on a first floor. Had me sleepless for quite a few nights, but after a yr that way with no probs. If I ever find a used tank about the same size, I'm putting it there again.
