I would clean the tank and remove the sealant and reseal the tank. watch this.....HOW TO: Reseal an aquarium - YouTube
Plus, if it was a reptile tank & not designed for water, it just may not hold up no matter how much sealant you put on. Sealant won't stick to sealant, so scrape off the old stuff real well? I'm not sure how to verify if it's just a reptile tank or aquarium worthy.
It was a fish tank before
