chip in tank - dangerous?
I have a 55 gallon glass tank. It got hit with a wooden block and now has a small chip on the inside of the glass, about halfway down. How big a deal is this? Is it an "OMG, replace the tank tomorrow or risk losing your floor!"? Or more of an "Eh, if it hasn't broken yet, it should be OK for the foreseeable future."?
If it's pertinent, I don't know how old the tank is... wait, yes, I do. The assembly tag inside was from 1997 but I bought it from craigslist.
Any thoughts appreciated,
