How old is this thing ? Its been handling your nasty-chemical-water for how long ? Plus, I don't believe this is a Godly issue. Father-time makes all the plumbing decisions. Forget any kind if slimey-paint or gummy-tape or souper-glue. J-B Weld would be my choice. But only if you clean the crack with a emery stone. Follow the dry-the-tank instructions. While it is air-drying, remove it, and go buy a new '''complete''' toilet. Most big home stores (like Home Depot) will allow returns on a complete toilet. That is Not always true for 'repair parts'. BTW: A complete toilet can be had for le$$ than a replacement tank.
