    Stains...not sure what it is...

    So near my pool steps I now have white marks, they appear like bleached out markings that occur only near the steps. They are smooth from what I can tell so I don't think it's calicum, but my problem is it seems like more and more spots are showing up.

    I'm attaching a picture. .

    Is there any chance that someone broadcast powdered "shock" or stabilizer granules into the pool? They'll leave white freckles if they sit on the surface too long. Even the simple action of rinsing the empty bucket with pool water to get rid of the crumbs could do it if they poured it out in that area.

    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!
