    Balanced or not or maybe?

    Just a little confused on the different way's to see if the water is balanced or not.
    My pool readings: 3 fc
    7.4 ph
    100 ta
    360 ch
    90 cya
    3950 salt

    If I go with the "Pool Calculator" it tells me it is at -.33.
    If I go with the "Langelier Saturation Index" it tells me it is at 0.
    And if I use the wheel that came with the Leslie test kit it tells me it is at 0 also.

    Pool is cyrstal clear but has a little scale comming from the swg when it does a cleaning cycle.

    Is -.33 close enough to consider the water balanced or am I doing something wrong?

    You are fine. You don't need to worry about the saturation index unless it is way off. Lowering TA just a little would be a good idea, both to reduce the scale coming off the SWG and to help stabilize the PH.
