    Bleach question

    The bleach I have is a store brand bleach thar says 7.86%.
    But I see alot of people reference 6% bleach.
    I will adjust using pool math....but was really just wondering why such a difference in %
    Even the clorox brand was 7.86% in my store. Maybe it's a regional thing?

    Yep, different regions different rules and different percentages. It varies from 6 to 8.25.

    Recheck the label. It should say 8.25% sodium hypochlorite. It also says "yields 7.86% chlorine". Everybody on this site would say your jug 8.25% bleach. And PoolMath expects you to use 8.25% as the bleach percentage, not 7.86%

    You should also learn to read the date code on your bleach jugs. I don't buy bleach that is more than 30 days old. This link should help you with that.
