    raising ph for the first time

    This is my second summer with a pool. Last summer all my levels were too high; this summer everything has been a bit low. My pH has been at 7.0-7.2 for over a month. I just raised my TA yesterday (it's now at 110) and am working on raising my CYA (it was at zero, just added stabilizer). After testing today (I have the TF-100) my levels are:
    TC - 6
    TA-110
    pH-7.1
    (I didn't test CYA because I know it takes awhile for the stabilizer to read)

    Should I add borax to my pool, based on the pool calculator? Or should I wait a few days and see if the baking soda I added raises the pH anymore? (Does it take awhile? Or would I know by now?) I know the borax can also raise the TA, so I'm not sure the best way to proceed right now.

    Thanks so much in advance for help! This community is so amazing/helpful.

    I would wait a few days, especially if you are swimming and splashing, that will raise PH.

    Baking soda doesn't raise PH much. More on pool chems here, Pool School - Recommended Pool Chemicals

    I'll wait and see if it goes up. I knew baking soda didn't raise it much, but I thought maybe it would contribute a bit to it. Thank you! I appreciate the quick response.
