    Can't keep Chlorine up

    FC -.5
    CC - Can't test
    pH - 7.2
    TA - 70
    CH - Can't test
    CYA - 50
    Borates - no borates

    After opening the pool last week I can't keep the FC up. I shocked(using bleach) last night using the pool calculator's suggestions.

    The water looked very clear this morning(It was only a little cloudy before) but the FC barely registers at .5

    The CYA is at the top of the recommended level.

    Should I try to lower CYA?? Any suggestions?

    More Chlorine!!!

    Seriously though, the bleach you're putting in is probably correct, but remember that chlorine is consumable. That is, if there are organics in your pool, the chlorine you're putting in is literally getting used up in minutes.

    Reread "Shocking Your Pool" in Pool School (upper right hand corner of every page), and remember that "shocking" is a process that could take some time.

    What kind of test kit are you using?

    Thanks,
    I am using the HTH 6 way kit mentioned as an alternative. (budget won't allow the others yet)

    I will keep shocking.

    Thanks guys,

    Shocked one more time and things are looking great. Still wished I would have paid a little more for the better test kit.

    Maybe next time.
