Hey guys I am looking to finish up a 450 gallon acrylic build 10x3x2 tall and made a mistake. I have the bottom, front, back, and both sides installed, but I accidentally had the lid cut to fit inside the rim of the tank and not on top. Any ideas on how I can brace the top with this smaller sheet? Maybe euro bracing? This is an acrylic aquarium. Top and bottom in 1/2" and the rest in 3/4". Any help would be great thanks
