    Re: vitamin C

    dollar store sells fruit drinks with 100 percent Ascorbic acid as the only ingredient would it be ok to try to use this since is mostly just food coloring a few ingredients for taste and mostly watered down vitamin C? What places not online can i actually buy Ascorbic acid?

    The concentration in the fruit drinks is going to be way too low to be practical. You can often find bulk ascorbic acid at health food stores.

    Some pool stores will carry it, such as Leslies, but it will be more expensive.

    Re: vitamin C

    im having a bit of trouble with the AA treatment that i haven't started due to making sure i have all the information first.

    Is that "metal free" stuff at the pool store the sequestering agent?
    I should apply the sequestrant first?
    How much per 10,000?
    When will it be safe to swim once I start the AA process?

    Most of this is answered in the link Jason gave you in his post on Monday.

    It will be safe to swim again when your pool is rebalanced.

    Metal Free is a sequestrant, but it is not one of the ones we recommend using. Other than that, see the topic I linked to in the second post above.
