i left a 10gal in my garage..... with 4" of water in it. 

there is now a single crack stretching from 4" high on the back wall to the top of the back wall, going diagonal.there is a plastic frame on the top of the tank as is with all 10gals. my question is, can i still keep water in the whole tank or is the tank no good now? can i fix it somehow?
