Thread: Still Foggy

  1. Back To Top    #1

    Still Foggy

    My numbers

    FC 4
    CC 0
    pH 7.2
    T/A 80
    CYA 30

    Should I add some baking soda to raise both my pH & T/A?

    1. I would leave your pH and TA alone

    2. Baking soda will not raise your pH but will raise your TA.

    3. What's still foggy? Your water?

    Re: Still Foggy

    My pool water is murky/foggy but blue.

    When I checked the pool calculator it sais: Note: Adding baking soda will also raise your pH


    Do I just need to wait?

    Hi, Lori,

    Good pic...that helps

    The murkiness will probably slowly go away simply by filtering as you suggest.

    It would probably be a good idea to elevate your FC level up around 6-8ppm as long as the cloudiness is present. That way, if you still have some living organics contributing to the cloudiness, the additional chlorine should help the clearing process go a little faster.

    I misspoke about the baking soda....I'm sorry. That said, I would leave both TA and pH right where they are.

    Baking soda only raises the PH a tiny amount. Normally you can ignore that.

    I agree with duraleigh, raise FC to just over the high end of the normal range and see if things improve day to day. If your FC level is falling quickly, it might be algae just getting started. It would also be a good idea to do a CH test, just to make sure your CH isn't really high (which could cause the cloudiness).

    Re: Still Foggy

    Can you lower your CH w/o draining water?

    I will test in the morning and post my results.... I have a funny feeling that is what it is.

    What range do I want to be in?

    Thanks for your help

    The two ways to lower CH are to replace water or to get a reverse osmosis treatment.
