    pH and TA

    I've had phenomenal results using the TFP method the last 3 years. Looking forward to a fantastic TFP season.

    We just opened our pool this morning and here are the results

    FC 0
    CC 0
    pH 7.5
    TA 40
    CYA 0

    The pH is perfect should I adjust TA before I start shocking.

    I will place some granules in a sock at the return to raise CYA.

    Thanks, Hannah

    Re: pH and TA

    If your TA really is 40 ppm then you probably do want to raise it at least a little. First thing I'd do is retest it.

    how old are the reagents?

    Re: pH and TA

    Chlorine and pH testing are from last year, CYA liquid, this year, the remainder 2 years.

    thanks for the quick response

    Re: pH and TA

    Since the reagents for TA are two years old I might get a second opinion before you adjust it.

    Re: pH and TA

    I retested at 3 pm after adding baking soda

    FC 3
    CC 1
    pH 7.8
    TA 70
    CYA 0

    should I adjust the pH?
    I added conditioner already.

    Re: pH and TA

    How does your water look?

    As for adjusting ph...since your TA was low (were you/are you using trichlor pucks or dichlor?) I would wait and see what your ph does. If it goes up at all, I would then lower it down to 7.5 or so.

    Re: pH and TA

    I've been shocking for 5 hours now and the algae/water is starting to turn milky gray. I will not adjust the pH anymore everything seems to be on course.
    do you agree?

    Yes, proceed with the shocking process.

    Re: pH and TA

    The pool is getting clearer. However this morning I performed 2 readings
    9 am
    FC 11
    CC .5
    pH 7.5
    TA 70

    10 am
    FC 8.5
    CC .5
    pH 7.3
    TA 70

    also CYA still registers 0. I only put in about 16 oz of conditioner, should I put some more in? and should I increase the pH levels.

    Thanks

    Re: pH and TA

    16 oz of conditioner/CYA is nowhere near enough. 16 oz in 22000 gallons would raise CYA by 6.5 or so, and you want to raise CYA up to the 30 to 50 range.

    With CYA that low you will lose chlorine to sunlight very rapidly.

    Re: pH and TA

    should I add a full 4 lb bottle of conditioner. I remember from last season, starting out with 0 CYA in the pool and adding less than a 4 lb bottle initially, I ended up with CYA levels of 30 during the season. I don't use any tabs.

    Also, should I raise the pH?

    Re: pH and TA

    Put in all 4 lbs of conditioner, if your pool volume is correct then it should only raise it a little over 20.

    Leave the pH alone, it is ideal for the shock process.

    the water is crystal clear now yesterday it was filmy. I think I'm done shocking.
    should I adjust the pH now. or wait for the CC to lower.

    Thanks for your help,

    Re: pH and TA

    Keep the FC level at shock level until CC is 0.5 or lower for 12 hours (or more).

    Re: pH and TA

    Just tested the water 6:40 pm

    FC 8
    CC 0
    pH 7.2/7.1
    TA 80
    CYA 20

    I'll be gone until Saturday night, should I raise the pH now, should I leave it?

    I will now add 2 jugs of 6% bleach just in case.

    Who is in charge of thepoolcalculator.com? Great Value bleach now comes in 121 oz jugs, not 128 oz.

    Thanks for the great site
