DIY acrylic thickness

[becks]

I'm about to start a new project; an acrylic lagoon tank. However, I can't find any online calculators that are working.

Open Top
Tank length: 24"
Tank width: 20"
Tank height 13"

Will 8mm be sufficient or will I still require 10mm?

I would go 10mm.

without a euro, 2.5x the normal thickness. So for 13" height which would normally be 1/4", you're up to 3/4" thick walls essentially.

The calculators made by the manufacturers are pretty much worthless btw when it comes to aquarium building.
