After being inspired by the last PMAS meeting I've decided to build my own frag/growout tank. Im wondering if anyone knows of a glass shop that can cut good square pieces. I've had glass cut by several places that was lacking in its accuracy. This wasn't a big deal for baffles and my overflow but could be more problematic with a tank. Im confident i could cut the glass, just not confident it would be square. Any suggestions would be appreciated. Thanks.
