Acrylic tank build question

[Hellothere12]

I'm looking looking to build a small frag tank hopefully going to do 36 x20 and 12 tall do you think quarter inch acrylic would do the job with three braces?

I would go 9mm

How about 48"L 18"W 18"H and 72"L 30"W 12"H ?

There is an excel file floating around the interwebs that is an acrylic thickness calculator. It’s fairly conservative and works great for what-if scenarios like this.
