I wonder how thick this "glass" is?

I've seen it and it's impressive!!!!!

Monterey Bay Kelp Forest Aquarium


did some quick research... monterey aquariums acrylic wall is 7.5 inches thick, to support water pressure at 16' depth. san diego plastics inc sells 4"x4'x8' acrylic sheet for $8437 each! not cheap...


That's why I was asking about the budget. You would probably need less thickness, but the knowledge of how to install it and the manpower that would be needed to install it would be beyond most homeowners capability. So, you'd have to hire a pro that was well versed in making large fish tanks.
