    CH Too Low??

    Current numbers:
    Date 8/23/14
    FC - Free Chlorine 3.6
    PH 7.5
    TA - Total Alkalinity 70
    CH - Calcium Hardness 100
    CYA - Cyanuric Acid 30

    Based on the recommended level of 220 - 350, my level seems low.
    Is this an issue?

    Thank you!

    For a fiberglass pool, you should not have a problem.
