OK, lol, I've moved a 220 glass tank by myself a couple times and it was extremely sketchy, difference was, I have a forklift. I would never even come close to trying something as stupid as a floor jack,foam, and tables. I had a friend who lost his life in front of his 3 year old daughter by slicing his femoral artery while trying to move a 150 gallon by himself, it's all I can think about anytime I get ready to move a tank.
