    Five Brown Stains at Deep End - Trichlor and Ascorbic Acid No Change - What Next?

    I have five brown stain at the deep end of the pool ranging in size from 1/2" to 2". I tried scraping trichlor pucks on them and letting it sit until the water dissolved it away. I tried laying trichlor pucks on them for several minutes. I put crushed Vitamin C tablets in a sock on them for 15 minutes. I've brushed them. No change.

    What would be the next step?

    Post up a picture so we can see what they look like.
    Do they have a different texture than the rest of the pool?
