    Switching to bleach this weekend

    We are having a mess load of people/kids over for the UFC fight this Saturday. My floater is just about empty and I have 4+ gallons of 6% bleach on standby. CYA has slowly climbed *just like you all said it would* to what I think is a good level.
    My current numbers
    FC 5
    TC 5
    CC 0
    pH 7.6
    TA 100
    CH 200
    CYA 65ish
    I've been using the aerator at night to keep a few degrees knocked of the temp of the pool but it doesnt seem to affect anything .......yet
    Thanks as allways for all the help and this saweeeet website!

    FC = 5 is your minimum. You should Target 10 when you add chlorine so it is still over 5 the next day when you add chlorine again.

    With your TA is a little high, coupled with the fact that you are now using bleach, your pH will tend to drift up. Regular additions of muriatic acid to keep your pH in check will eventually bring your TA down pH will become more stable.

    CH is a little low.

    CYA is high, but not unmanageable.
