    Sounds like calcium scale. Enter all your test results in Pool math and it will calculate your CSI. Keep it negative -0.3 to 0. Tweak PH and/or TA.

    Re: white spots on vinyl liner

    would Calcium scaling remove the color from the liner?

    Does calcium scale happen on vinyl? I was under the impression it didn't stick to vinyl.

    I don't know if scale can remove color, it doesn't seem like it should. Yes, scale can definitely stick to a vinyl liner.

    Re: white spots on vinyl liner

    There a couple of options in the link I provided. You can also put dry acid in a sock for isolated spots.

    Re: white spots on vinyl liner

    my pool installer thinks it is a defect in the liner itself, which has caused it to loss its clear finish over the print. sending pics to the manufacturer to see if warranty will cover it. pool is not yet 2 years old.
