Im on one of the last steps till finishing my plywood tank, the glass instalation. The tank is 240 gallons, 8-2-2ft, and the actual panel of glass will be around 94"-22"-22", and 1/2 inch thick. My question is how many inches of the glass needs to be resting on the front framing of the tank on all sides so its stong enough. Right now i have a framing of 2 by 3's around the tank, which will give the glass around 2 inches to rest on, but was thinking 2 by 4's will be better. Let me know what you guys think.
