    (Stupid?) Question on reading TA test

    The last few times I've tested for TA, I put in the buffer drops and the drops that turn the sample green. I get to 6 drops of the reagent and after swirling the red disappears and we still have a green solution in the vial. On the 7th drop and the swirl, the green disappears ... But no red...we essentially have a clear solution in the vial. On the 8th drop of the reagent and swirl we then turn the full red.

    So is my TA 70 or 80?

    What happens at drop 9? If there is no change from 8, then 80. Keep putting drops in until there is no change and at that point disregard the last one you put in.

    No change at the 9th drop.
    So I guess I will go with 80.
    I've been thinking it was 70 since that's what got rid of the green.

    ALL the tests (FC, CC, TA, CH, salt*) are done until the last drop causes no further color change and that drop does not count.

    *For the salt test, I think you are done at the first appearance of red and with another drop it goes brown. I am not 100% on this.

    Re: (Stupid?) Question on reading TA test

    Ok. Thanks. I've added some more acid to dump the TA and will allow it to aerate back up. It's all in balance even with the level of 70 or 80, but I can get it tighter.
