Gator;4728444; said:I used a tempered piece that was 78"x29"x.5" and there is no bowing and its been fine for over 2 years. But if you plan on having a piece that is 36" high then I would step up to the 3/4" thickness that everyone is suggesting.
right, on my build witch was 29inches tall i used 3/8 tempered. but 36inches tall is a ton more psi in the bottom 4 inches of the tank IMO
