    Just Received My TF testkit and TA is high

    Just did the test and here are my numbers:

    FC 6
    CC .5
    TC 6.5
    pH 7.35
    TA 200
    CYA <20

    My chlorine burns off quickly. I assume this is due to the low level of CYA. I am going to purchase some more today as I only purchased 3lbs of it for a 22000 gallon pool. I was battling algae, but with a CC of .5 I think that is done with. My question is the TA seems to be really high. Should I worry about it? Also, should I try to raise the pH to around 7.5?

    Thanks,
    Nod

    Nod,
    CC of 0.5 is not that uncommon for a "normal" pool, also could be the error allowance in the test. You defintely need CYA up to 30 -50 ppm. Your pH is fine for now (7.2-7.6 is ideal).

    Your TA is high, which means your pH will probably drift upwards with any aeration (rain, splashing, etc.). There is an article in the Pool School that addresses lowering TA HERE, but first, make sure you are familiar with the basic chemistry balancing articles in the Pool School.

    Please let us know if there is anything else you need help with!

    For your TA, did the drops come out slowly for R-0009 or were they small ones that were difficult to control? If they were the later, then your TA reading will be inaccurate. See this post by Dave about that issue:

    I did notice it was hard to control the drops and they were a lot smaller. Thanks for the info! I will recheck now.

    Ok, Just retested and not sure if I read the test right. It was a light shade of pink at the top and pale green at the bottom - another drop made it red (light red) That was 12 drops x 10 - which would be 120.

    That sure sopunds like one of those defective tips......and they're showing up in the R-0009's which pretty much confirms it.

    Nod, please confirm your last name to me, and I'll get new tips out tomorrow AM. Reread that post KTDave referred you to about how to replace them and how to do the test 'til you get your tip(s).

    Again, I'm really sorry for the innaccurate test results this has put some of you through.

    Re: Just Received My TF testkit and TA is high

    Since TA level is at the high acceptable end (120), should I just let the normal affects of swimming and aeration do the job, or should I try to lower it? Right now my pH is 7.35.

    With TA around 120 you might as well leave it alone for now and let it come down naturally.
