Glass Thickness For Large Tank

[justincgdick]

I'd go 3/4". Go as long as you want... it's the height that determines the glass thickness due to pressure. You may need a thicker bottom, I'm not sure.

If you get to 24" or less in hight you could probably drop to 1/2", IMO.

Actually length is a major contributor for glass thickness, the longer the tank the larger the bending moment which results in more deflection.

For the size 5/8" min for sure but 3/4" would be better. A standard 230 is 72" x 30" and uses 1/2" but they show a noticeable bulge as a result. With 8 feet and 5/8" you may notice a similar effect but it still be perfectly safe but the deflection causes some slight distortion which can be annoying to some people. It also depends on the bracing.

My 300 ( 96"L x 30"H x 24"W ) is 3/4" all sides, euro-brace and bottom inside cleats ( front & back )
