I have a 14g rimless cube currently set up as freshwater that I'm tearing down and would love to set up as saltwater. I'd like to try and finally set up this tank with a refugium but haven't been able to get a clear answer on whether I can drill it safely or if the glass is tempered, preferably I'd like to drill the bottom. Has anyone successfully done this on this tank?
