    How long does Bleach stay usable?

    Hi,

    So i am ready to fill my 30 gallon tank to give my pool LC with the stenner pump. I am a bit curious how long the bleach should be good until?

    it is really cold in NY & I dont expect i will be using much bleach for the next few weeks. My pump does 1oz per minute & It probably will use a gallon a day during the warmer part of the season (+/-).

    Can it sit for two months without going bad? It is indoors in a sealed container.

    Thanks,
    Rich

    There's a chart at the bottom of this page, and it also has a link to some more technical stuff. http://www.odysseymanufacturing.com/about_product.htm
    16K freeform gunite with spa; Pentair 4000 DE filter; Century Whisperflow 1 HP; Pentair Minimax heater.
    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, but it will be 2.5% bleach at the end of the year.
