    Re: Chlorine/cya chart

    Given a CYA of 70ppm, you need to keep the FC above the minimum (5ppm) at all times ... that is the most important thing to realize from the chart.

    Note that CYA does not change very quickly unless you are replacing water. May only need to test once every few weeks or a month.
