    help, I have a salt water pool that has stains that cant be identified. Pool is marcasite only 6 years old. I've tried 2 different test kits but they both failed to identify the stain. I tried every chemical know to man to remove these stains. Any suggestions.

    Welcome to TFP!!!

    Please post up pictures of the stains.

    Try putting a crushed up vitamin C tablet on the stain for a few minutes, if it lightens, it is metals.
    Try putting a trichlor tablet on the stain for a few minutes, if it lightens, it is organic.
