    Pool Chemistry question

    I was opening my pool the other day and it turned really green. Shocked with liquid chlorine and was a little heavy handed with it. It cleared up algae but now its super cloudy. Stayed cloudy after 24 hours of filter running. I used a Tf100 kit and got these numbers.
    Here are my numbers:

    FC-20,5
    TA 140
    O cya
    PH 7.2 ( i understand high chlorine gives false ph reading)

    Any help is appreciated

    You're Waaaaaaaaaaay over your FC requirement for a SLAM with zero CYA in there. Let's get enough CYA added to get you to 30 ppm and SLAM at that level. Please add a signature line to your profile listing your pool stuff and equipment. Have you backwashed/cleaned the filter any? You also list no CC for us.

    Welcome to TFP

    Great job on getting the TF100, its a great kit..

    Lets get that CYA up from walmart
    let your FC drop to 12 and start your SLAM from there, keep your FC at 12 as much as possible

    As of Sunday the 22 my fc was down to 9, my cc was 0 and my ta was 130. Pool math said to add 54 oz of stabilizer. Was able to add half that amount. Need too buy more stabilizer. Still Cloudy though.

    Yes, raise pH before starting SLAM, then print this out and put it where you test. Pool School - Chlorine / CYA Chart
