    "staining" on bottom of pool

    I have an in ground saltwater pool with a bluish pebbletec. I have what appears to be a brownish staining on the pool bottom. It does not feel slimy but cant seem to brush it away.
    Any idea what this may be?

    Welcome to TFP! Could be tannin stains from leaves if they have been there a while, or could be iron stains. Do you use well water to fill your pool? Could you post a complete set of test results?
