Chiped Tank

[jmon777]

i was trying get some crappy gravel out of a 30 gallon tank (never buy the dyed stuff from a chain store) and to get the last bit out of the tank i tipped it up on the bathtub and it it chipped the sides of it but it still holds water fine. but in about 3 spots on the side are chipped about half way through the glass. should a i patch it with something or should i just throw it away?
