    Calcium hardness rising

    Ok so I've been testing with my new TF100 kit since Saturday. Starting to get the hang of it. Got a speed stir and that's fantastic.

    Here are are my original tests from Saturday morning:

    FC- 6
    CC- 0
    Ph- 7.9
    TA- 150
    CH- 350
    CYA- 90

    took the tricolor out at this point and started adding bleach and MA, while aerating to bring TA down and increase FC.

    My my readings tonight are:


    FC- 10
    CC- 0
    Ph- 7.7
    TA- 110
    CH- 400
    CYA- 80-85

    Why is my calcium hardness rising? I know it's still in the acceptable range but was curious why it's rising?

    2 drops difference? Likely within the noise or minor testing error. I would not worry about it and see how things continue to trend.
