So I got a new 65G that I'm using for a reef tank. It come with a tower overflow and is pre drilled. On the bottom, there is a chip under the overflow box area...it's not a hairline crack or a crack at all. The glass is quite thick (0.25 inch) But I'm worried it might leak, even if it is under the overflow area where it will not suffer from too much water pressure. Any advice is appreciated.
