I just got a tank on a trade and wasnt made aware and didnt see a large crack in the outer later of the tank. This tank will need to be retested come June. Will it pass? Its not deep and isnt loose like you can get something under it. You can just feel it on the surface. The small slit by the label you can get something thin like a knife in there but not deep.I want to know if i have to send this back to the trader or if it will pass.
