    0 CC is always OK.

    Areating to lower carbonate alkalinity is also OK.

    If you are having rusty backwash, that's ALSO good -- that's iron leaving your pool!

    Where do you want to go from here? Are the remaining stains ON the pool bad enough to be of concern? Or, do you just want to clear up the pool, and get on with using it?

    By the way, if you'd go here:

    and add information about your pool -- gallons, pool surface type, pump & filter, chlorine feeder or SWCG -- that will help those posting answers 'get it right'.

    Thanks for the reply, I have updated my signature line. As of today:
    FC 9.0
    CC 0.5
    TC 9.5
    PH 7.0
    ALK 140
    CH 80
    CYA 55

    My well water has an ALK reading of 370, so I want to get my pool's down to about 90 or 100 so it wont be sky high when I finish topping off my pool. I have about 2 inches to go.

    I am not too worried about the small amount of staining, but I would like to try to remove them. I purchased 1.75 pounds of Ascorbic Acid and I'm not sure when I should add it. Can I use the AA to help in the process of lowering my ALK or should I get my ALK to my desired levels first?
    17,500 Gallon above ground, Hayward 150 pound sand filter containing 75 pounds of Zeobright, 1.0 HP pump, Rheem natural gas heater
    My results are generated from a Taylor K2006 kit.
