tint would have been a sweet idea,,,, i like the painted idea, i think I'll be ok, worse comes to worse I can always scrape, and what you mean I only had to support back and front? i basically built 2 walls, and they connected to each other lower down, its 4 inches by 4 inches front and back leaving about8 inches in the middle , the tank really will be fine, its not going to cave in lol, i could park my car and that wall I built, the tank filled with rock should be close to 1500 lbs, but its also on a basement floor so... its not going anywhere, trust me on that.
