    Staining trouble shoot

    Need to trouble shoot these stains. The plaster is a little scratched/chipped and where to does there are brown stains. This only occurs around these scratches. I am in the process of selling the house and want the pool to look as good as possible. Was re plastered in 2010. Water specs are usually kept normal per the pool calculator app, but I do have higher than normal calcium, but tend to keep the PH slightly acidic per previous direction that you can live with higher calcium levels in a pool.

    Any ideas what to use to test what would take them off?

    If they are due to some sort of metals in the water, a vitamin C pill or two would confirm it.

    Put a couple in a sock or something, and hold it down on the stains. If the stain is lifted or noticibly lighter after the Vitamin has dissolved, then the stain is due to metal.

    The same test can be done with a chlorine puck for suspician of organic staining. (hold the chlorine puck on it for 10 minutes or so).

    If the discolored spots are raised and very rough to the touch, it may be "calcium nodules" that is the problem.
    See this post: http://www.troublefreepool.com/threa...dules-in-Pools

    Sanding them off with wet-or-dry (100 grit) sandpaper may work best.
