    Old Bucket of Cal-Hypo

    Just had to take over operation of a community pool. There's no one to tell me the history of any of the chemicals in the storage room, so I don't know their age. There's a huge bucket of granular Cal-Hypo that's about 2/3 full, and I'd like to use it due to low CH. But can it be relied upon or should I purchase new? Hate to spend that money, and also not sure how to safely dispose of the bucket if I can't use it. If stink is any proof of potency, I can tell you it's plenty strong. Took the cover off to see if it had caked and the smell fairly drove me from the building! But seriously, it could be a year or more old and I don't know if that's a problem.

    If it was kept dry in the bucket, it's still good.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    Yes. Minimal caking. Glad to hear it's probably OK.

    OMG the smell is potent. I'll take it outside on the hand trucks before opening.
