    Chasing the perfect TA

    Thanks @Msch99! Makes sense. I'd rather achieve my target CSI with a higher pH / lower TA as it'll fluctuate less, require less MA, and be more in line with what my SWG prefers. Based on your feedback and a couple others up here, it's clear I was not going low enough since even at the TA 80...

    Chasing the perfect TA

    @JamesW thanks again for the insight, makes a lot of sense. Great to know Pool Math accounts for the effect. I will treat the TA target as real and not try to compensate manually based on CYA. I ❤ Pool Math! Update: After I started this post a few weeks back (at pH 7.4 / TA 90), I did the...

    Chasing the perfect TA

    Thanks for the thorough explanation @JamesW! Very interesting. So are you suggesting that at a pH of 6.88, the other half of the cyanuric acid molecules have <3 hydrogen ions (e.g. cyanurate) and thus do contribute to the TA? Or are you saying that the net effect is no change? Does anyone...

    Chasing the perfect TA

    Thanks @mas985 . You've actually been a source of comfort in my past learning of the ABCs because I noticed you had a similar setup and also were in CA where we have traditionally high TA/CH in our fill water... I've been admittedly dosing more acid these past few weeks trying to see if the...

    Chasing the perfect TA

    Thanks @Jimrahbe ! I'll take that as a +1 on "stop chasing the number". :) I do my main pool maintenance on the weekend, thus a weekly regime, so I target 7.4 as acceptable pH knowing it'll be around 7.8 by the next weekend. I'm also largely trying to manage things to a slightly negative CSI...

    Chasing the perfect TA

    Thanks @Richard320 , that's helpful re: CYA showing up as TA. Would the inverse also be true, e.g. in my pursuit of the perfect TA did I in fact neutralize CYA and TA? This goes against what I've learned about CYA in the ABCs, but I may as well ask...

    Chasing the perfect TA

    Hello fellow TFP members! I've been following the TFP methods of pool chemistry for 3+ years now and love everything about it, the quality of the water itself being paramount above all else. I've read the ABCs several times and understand both the target levels as well as the qualitative rules...

    Loss of CYA over Summer

    Ok, thank you. Great advice. I think at the end of the day, my lesson here is that CYA actually does dissipate and I need to monitor it more frequently like you say. Good to know!

    Loss of CYA over Summer

    Thanks @mknauss! I've been following your ABCs since pool construction in 2016 but this is my first post. ;) Love you guys and have turned a number of fellow pool owners on to your fool-proof methods. We admittedly keep our pool on the warmer side, so it makes sense we'd see an effect here...

    Loss of CYA over Summer

    I had 75 ppm of CYA in March and tested it again yesterday to find it was <15 ppm using Taylor K-2006 kit. I am confident in my test ability, but don't normally test CYA due to historical experience that once stable, it doesn't go away without water change. Like the others here, I am confident...
