    Can Scaling dissolve with positive CSI?

    Hi,

    I've noticed that over the last few weeks, the scaling in my pool seems to be dissolving slowly. If I rub the scaled areas, a little cloud comes off, and when I brush, it does the same thing. Here's my recent numbers:

    FC 5
    CC 0
    pH 7.6
    TA 120
    CH 400
    CYA 80
    Salt 3330
    Water temp 88

    CSI shows to be +0.14

    Is it possible to have the scaling dissolve with a positive CSI?

    Thanks!

    Yes and no. Calcium scale will not dissolve in the usual sense when CSI is positive. However it can crumble, breakdown into dust, or flake off.
