    pH and Chlorine

    Hello Friends -
    At what point does chlorine have an effect on pH measurements? My current FC is 17.5, and pH measures 8.2, and I'm wondering at what level of chlorine can I trust my pH measurement before I adjust with MA.
    Thanks...

    above 10ppm fc makes ph read falsely high.
