    Default Re: Super high combined chlorine

    So, do you think FC should be higher than 15 upon closing? I plan to have my CYA in the SWG mfr recommended range of 50-75 ppm. Looking at the best guess CYA chart on this forum, that would correspond to a shock level of about 20 ppm FC.

    EDIT: not sure it matters, but I also have a Nature2 cartridge.
