    Welcome to TFP!!!

    Looks like calcium scaling to me ... from letting the pH stay too high with high CH levels.
    There is no way this just appeared over the winter above the water line. Must have been on the surface when the water was still full.

    Usually you need to acid wash ... although I am not sure if that is what is done for a vinyl pool too.

    Looks like Calcium scale. Mix up some 1:3 Muriatic acid and water and squirt it on a small section. Calcium will foam up and dissolve. If it does, someone's got a whole lot of work ahead of them.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!
