Hey all, I have a DIY sump project that REQUIRES a custom built tank. I know it's cheaper to buy tanks and all that, but this one needs to be a certain size so I'm looking for input on thickness. The tank dimensions are 12.185x10.25x9 inches which is I believe in the 4-5 gallons of capacity range. Will I need 1/4" thick acryllic or can I use thinner and still support that wieght of water? Thanks for the oppinions
