    Strange dark grey / black algae on my pool liner. Removal advise needed.

    Hi All,

    Near the very top of my above ground pool liner I have some dark grey / black spots of what I can only assume is algae. I have tried to remove it from the surface but it simply won't budge. Does anyone what this is and more importantly how I can get rid of it?

    Thanks
    Daz

    Sounds like something "soaked in" to the liner, or its behind the liner.

    If it's behind the liner then what product should I use to try and remove it. I could release the liner quite easily as I haven't filled the pool up for summer yet.

    What have you done so far to try to remove it? What does it feel like? Pics might help.

    Hi. I tried last summer to remove it with some bleach but it didn't budge it. It feels like it's part of the vinyl like a stain. I haven't tried opening up the liner and attacking it from behind yet. I'll try and post a pic when I get home tonight.
