    Ph level opening pool

    Inhave a donut pool. It's 3750 gallons. I just added stabilizer to get my CYA to 40 ppm. My TAia 110. FC 4ppm. I use bleach. PH is 7.2. My question is should I even try to adjust the ph since cyanuric acid lowers PH and mine isn't even fully dissolved yet. Should I wait until water is balanced or go ahead and raise Ph? I want to add 30ppm borates too. So I don't want to do anything to raise my TA if I don't have to. What should i do?

    You are fine where you are in my opinion. I'd bet your pH will creep up naturally with TA at 110ppm.

    Last year mid season I decided to add 30ppm borates and I really liked it. At that time my TA was almost 200 and it took me forever to lower it before I could add borates. Now my TA is only 110. Would be hard to lower it to 90 and add borates. Should I do it now or wait until the pool stabilizes more. I just filled it yesterday. I just don't want TA creeping up and making more work to add borates.

    I'm not sure I understand. TA won't go up unless your fill water has high TA or you add baking soda.

    Apparently my fill water has a TA of 110. I just filled pool yesterday. My ph is low at 7.2 but I just put cyanuric in yesterday (solid put in a sock to dissolve). It's almost fully dissolved. I know it lowers PH. Domi adjust PH now? Can I start adding borates since the PH is already low and TA is borderline? Do I wait a few days before doing anything?

    I agree with JohnT above. Wait a few days to see what it does. It could be that CYA lowered pH, but natural rise brought it back up. It also could be that the pH will rise to 7.5 and stabilize because that's the equilibrium point.

    I vote for don't rush and learn the pulse of your pool.
