    Question TA test affected by FC ?

    TA test affected by FC ?

    Hello,
    Before slaming, my TA was 90 ppm (i count 9 drops)

    Now, at FC of 5.0 i only count 5 drops for a TA at 50 ppm .

    I dit not refil the pool, nothing. I only add this morning 1kg of borax to ajust pH

    I always test in 25 ml, add 2 drops of reagent 7, 5 of reagent 8 and after i count each drops
    Also, i have some reagent left from last season, and i got the same result (5 drops)

    There my actual result:
    FC= 5 ppm
    CC=0
    pH= 7.5
    TA=50 ppm
    CYA=0

    Thanks helping me

    FC level will not affect the TA test. Very high FC levels may change the colors, but the test is still valid.

    one of the tests must have been wrong.The TA can have static in the bottle giving higher result, you should wipe the tip between drops.

    I forgot to tell my pool have 30 ppm of borate.

    So the first test must've been wrong. The borates will not have an impact.

    You didn't lose 40 ppm of TA, the first test result must have been incorrect.
