    Pool Math Calcite Saturation Index - Should I be worried?

    I'm always off on the Calcite Saturation Index and I don't know if I should be concerned. Here are my numbers:

    FC: 5
    CC: 0
    PH 7.6
    TA: 80
    CH 350 (our pool is 9 months old. we started at 290 and it has crept up slowly)
    CYA: 45

    When I put all of my numbers in pool match my Calcite Saturation Index, I get 0.21 and it says "Greater than 0.6 is suggestive of problems for all pools."

    All of my numbers are within accepted leveles, although I know 350 is on on high end. The area we live in has high calcium levels in the water.

    Is there something I should do?

    Thank you!

    0.21 is lower than 0.6. Anything between +0.6 and -0.6 is OK.
    You are fine.

    Ah LOL I guess I just had a blond moment. I SAW .21 but thought 2.1.
    Thanks
