    Stains from pH Down?

    I added some dry acid last night and I think there might have been a couple of clumps. I noticed his morning two brownish stains. I tried to brush hem bit no luck. There are no leaves or anything in the pool.

    I added pH down and calcium.

    I am on well water. The stains seem like clumps of dry acid sat and dissolved or something.
