    numbers day after adding borates

    Added borates yesterday with the borax/acid method.

    Here's the latest,

    FC 3
    TC 2
    PH 8
    TA 140
    CH 225

    Will test the borates tomorrow.

    Should I correct the PH and TA now or wait another day to see if they come down?

    Re: numbers day after addding borates

    your fc and tc are off. did you reduce the ta before you added borates? I believe JasonLion has mentioned it is much harder to lower TA after borates.

    I did lower the ta and was surprised to see it so high.

    the 20 mule team borax I used raised my TA by 20 (from 80 to 100). have you read waterbear's post about halfway down the page in this thread?

    he talks a bit more about the ph.

    I would go ahead and lower the PH to around 7.5.

    thanks,

    what's up with the FC and TC is that a false low on the TC?

    Repeat the test.... testing error? TC cannot be less than FC. Not possible.

    Re: numbers day after adding borates

    Are you getting the TC reading from the OTO test (drops turn the sample various shades of yellow)? Using the OTO test it is very difficult to distinguish the shades of yellow for TC levels from 2 to about 8, they all look very similar and don't really match the color samples for 3 and 5. It takes a lot of practice, and comparisons back to the FAS-DPD test, to be able to read OTO values above 2.

    I'm using the Taylor Test kit from Leslie's.

    How long should I wait to retest after adding acid?

    When was your PebbleTec applied?

    You don't want to lower your TA too far before you raise the CH level. I would normally add CH after four to six weeks. But you don't want to do anything that would jeopardize the warranty.

    Re: numbers day after adding borates

    Thanks, that's what I was thinking too......keeping the TA high with the low CH. Once I can start adding CH, what would be a good TA and CH level to maintain?

    The pentair manual for the SWG recommends a TA at the high end of 120 but that seems opposite of the recommended levels on this site.
