    Does adding CYA make water cloudy?

    My water was sparkling yesterday then I added CYA in a sock hanging by the return and when I checked pool this morning the water is milky looking and cloudy, Is this Normal? If so how long do you think it will take for pool to clear up?

    Re: Does adding CYA make water clowdy?

    I don't think that would do it....but to help you better, we would need to see a full set of test results for your water. Do you have that, can you post it here? Then we can get a better idea of what's going on with your pool.

    Re: Does adding CYA make water clowdy?

    Ok I just went out and took a full set of readings on the pool, I shocked my pool wednesday evening so the fc is a little high and I got a false reading on the PH because of the high chlorine, here are the numbers.

    FC - 10.5
    CC - 0
    PH - 8.0 Due to high chlorine?
    TA - 120
    CYA - 35

    water was crisp and sparkling yesterday after shocking, I vacuumed and added CYA and today it is clowdy.

    Thanks for helping been struggling with pool this year and dont understand why

    Hi PH combined with high CH can cause cloudiness; what is your CH reading?

    If the pool is cloudy white then try bringing the PH down to 7.5 and see if that clears up the cloudiness.

    If it is cloudy green then it sounds like the algae is coming back.

    I have added several lbs of CYA via a sock.. never had an issue with cloudiness.
