    Is this a bleach stain on the liner?

    I normally pour the bleach in over the jets, but in the past I've had other people pour it in for me when I'm away. This stain was here last year and I'm not really too worried about it as the liner is nearing 15 years old. This stain goes from the top to the bottom in the deep ind and there is a distinct outline from where it is not stained.

    I'm assuming that its bleach related but thought I'd throw it out here.

    I doubt it is from bleach. If anything, the liner would be lighter if bleach was damaging it. It could be that you have some metal that is being precipitated by the high concentration of chlorine when you pour the bleach in at that spot. Try a vitamin C tablet on the stain to see if it is metal.

    John, I'll try this when I get a chance. All I can find are some Flinstone chewables right now

    Re: Is this a bleach stain on the liner?

    Well, I never did get around to doing the Vitamin C test. I picked up a Jack's Magic ID kit to see if that would tell me anything. I put some of the Stain Solution #1 (Iron, Cobalt + Spot etching stuff) in a pantyhose and dropped it in the pool. It left a clean streak on the wall as it went down. That stuff must work pretty well. I see you can get it in 1 and 2 pound jars. How much would I need to treat 24K gallon pool?

    Are there other options/recommendations?

    Read All about metal staining.

    There is a link to doing the AA treatment - in that article are the dosing instructions.

    Stain Solution #1 is the same as ascorbic acid.

    Another question...is there a preferred sequestering agent to use when doing the AA treatment?

    Edit...Nevermind, I see there's a post below discussing this
