tank build

[BigBadBlenny]

i am thinking about building a new tank. i want to try my hand at the construction myself. i am thinking about a 100 gal cube.
dim 30 x 30 x 24 tall. my question is how thick plexi do i need to build this safely with out bowing. i have access to 3/4" plexi used in rink boards.

any thoughts or comments

Hey if you have to 3/4 then I would use that. My 110 gallon has 1/2 thick glass. Not sure how glass and acrylic compare but I would think that would be thick enough. Hopefully some one who knows will reply.
