thanks for all of the info, I'll be looking for local plastic shop to cut my single piece to size. After that i have a few thinner pieces of acrylics to play with to try welding. This will be a long shallow tank that I think will be great. Probably going to put shop lights over it when i finally get around to getting the materials and space prepped for this. I'll post some pics, but i don't think it'll be a problem as far as materials go.
