I've been trying to find a clear answer in the DIY forum but still haven't had much luck. I'm thinking about making a ~30g, shallow, square-shape aquarium. My question is what type of acrylic would be good for this job and where can it be found? I went to HD yesterday and saw that they sell .220 inch acrylic made by optix (plaskolite.com). Also, I'll probably use a euro style brace for the tank.
