    Rust spots bottom of pool liner

    Hello,

    I dove down today into the pool with goggles and saw some rust spots. I thought maybe black algea but they didnt wipe away.

    questions,
    what is most likely the cause? and how do i know if its a big deal or a one time deal(or can this rust sort of expand..sorry if thats a bad question)

    is there a safe way to clean them (pool is obv full of water etc).

    As always thanks for your help

    I am thinking it was something in there over the winter. I've spent the last 30 minutes replaying the entire opening and shocking process. I think a brush may have been in there. But can it expand or is it a one off.

    Once the metal is removed, the stain should stop spreading. The tiniest but of iron or steel can leave quite a large stain. Some Vitamin C tablets piled on should lift it. Check out this picture:

    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!
