1" acrylic tank?

  • We are currently upgrading MFK. thanks! -neo
i have a question about acrylic thickness. im planning a 450gal plywood build with a viewing window 88x24 would 1" acrylic be enough or should i go with 1 1/4 or 1 1/2?
 
Thanks for all the input. Im thinking of going with 1 1/4" since it will have a 4" overlap on all four sides from a 4x4 post.
