Odd shaped acrylic build; is 1/4 enough?
I've got a very old Bench grinder stand that was built by my grandfather, I've used it to hold a 10g tank before but want something larger. I want to build a custom acrylic tank for it as practice before I commit to building the 250+ gallon acrylic tank for my new home. My maximum base dimensions are 20x12 and I'm thinking of building it 32" high. I know this is an oddball size and it should be a little over 30g. Will 1/4" acrylic be enough? The calculators I've seen don't make much sense, they call for 1/2" thick on this 30g tank, yet also say 1/2" thick is needed for my 250+ gallon I am building.
