    Some Adjustments?

    Not too bad but was wondering if I should start lowering PH and TA?
    I just added chlorine so it will actually be higher than what I recorded.
    thanks

    Not bad at all. TA & pH? ........ you could. Just focus more on the "consistency" of the pH though, holding better in the 7.5-7.8 zone, so that once you get TA where the pH doesn't rise too fast for your liking, then it's all good.

    Right - wait a few weeks to get an idea of how your pH drifts over time, and adjust TA as appropriate to counteract the drift. There's no need to adjust TA just to get the number right. I've found, especially since I use a solar cover that's on almost all the time, having a slightly higher TA than recommended helps keep my pH more stable - I haven't had to adjust pH for a month.

    Looks good, but watch that FC. At 50ppm CYA, your minimum FC level is 4ppm, with a target of 6ppm.

    At your next CL addition, go a few ppm higher so the next time you check you don't dip below min.
