Optimized Glass Thickness

All our standard aquarium sizes, special aquarium sizes, and amphibious aquariums have optimized engineering to determine the minimum thickness required for each glass panel. So instead of a one-size-fits-all formula, we optimize each panel based on engineering standards.

For example, say you go from the size (24“H x 72“L x 24”D) to (24“H x 96“L x 24”D). Most manufacturers would automatically increase the thickness of every panel just because one needs to be thicker, or they skimp on all panels because they don’t want to upgrade only some of them. Just because you made it longer doesn’t mean you need thicker side panels; You just need a thicker front, back, and bottom.

Our engineers used advanced pressure rating formulas to optimize every aquarium size to have a minimum safety factor of 2.3 (Industry minimum) but ours are even stronger because of our proprietary aluminum frame system. Using this technique, we achieve the highest strength at the lowest cost. As a result, our prices and weights tend to be more favorable than other tanks of the same size.

But keep in mind, that these are minimum standards. You are always free to upgrade any panel for additional peace of mind; they just can’t be downgraded from the aquarium size configurations above.
