...or, how not to destroy a new tank Never, ever drill a tempered glass bottom! I just found this out the hard way. Got a used 125 and decided to save some money and drill it myself for an overflow. I was about two minutes into it, using a carbide burred hole saw, when "SNAP!" The whole bottom spiderwebbed on me. Oh well, looks like I'll be ordering a new 125, reef ready.
