    TA almost doubled?

    So my TA has gone up from 110 to 190 in about 2 weeks. I added 40lbs of Proteam supreme and
    was curious if this is what caused the increase? Should I be concerned at it being that high? Everything else is spot on and seems to be holding well

    Test results

    Ph-7.6
    fc-5
    cc-0
    ta-190
    borates-50
    cya-28
    19k 15x36' inground oval vinyl lined pool with deep end. 3 returns , 1 skimmer, 1 main drain. TF-100 test kit

    Re: TA almost doubled?

    Let us examine the clues.




    Aha! The MSDS says it contains Sodium tetraborate pentahydrate and some kind of proprietary ingredient, likely dry acid to neutralize the pH incrase. Exact percentages aren't given.

    So... going to pool math and inputting 19000 gallons at the top and then scrolling down to Effects of Adding Chemicals... 640 ounces of Sodium tetraborate pentahydrate will raise pH by 5.62, raise borate by 37 and raise TA by <drumroll> 86.

    So the stuff isn't 100% and the acid cancelled the pH rise but the TA is pretty much in the ballpark.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    It would appear you are trying to mix pool store advice and TFP advice. It won't work!

    Is having that high a level of TA bad as long as my PH is spot on?

    Countpyro1? What was your intentions with the ProTeam Supreme? Was there some imbalance going on you were looking to correct? Or did you just want to add a water enhancer?

    I added it for the borates. They had it pretty cheap and wanted to give it a try. It's oh neutral so I didn't have to need with the Acid. Maybe it's Proteam supreme plus or what ever it's called. I know I could of done it cheaper with 20 mile or borax but had some gift store credit I had to use up so bought this instead.

    I think what he meant by pool store advice is that proteam plus could be considered a "potion."

    If your TA is high it's not really a concern for a vinyl pool other than the potential for faster pH rise.

    Re: TA almost doubled?

    No, generally having high TA is not bad. It will put upward pressure on your PH and it will rise faster. So, just keep a closer eye on PH and lower it as needed.
