    End of the season -- should I adjust water, or wait?

    First, here are my numbers:

    FC 3.6
    CC 0.2
    pH 7.7
    TA 140
    CH 270
    CYA 65
    Temp 78
    Sat 0.4

    My pH, TA, CYA and Sat have very slowly crept up to these numbers over the summer, and they're at the point where I'm thinking about adjusting (yes, I'm using BBB). But then, it's Wisconsin and we'll be winterizing fairly soon, so I'm thinking that since they're not in the danger zone, I could leave the adjusting until next spring when I'll be half refilling the pool with tap water. (By the way, I know nothing about winterizing - off to read posts now.) But then I thought, maybe there are risks in leaving these levels over the winter? Your advice appreciated.

    You numbers are reasonably good for closing. I would lower the PH just a hair, to around 7.5. Other than that you can leave it alone.

    Since my pH has gone up yet again (perhaps because of my new Pool Devil, which captures leaves and bugs but also aerates?), I'll follow your advice and lower it. Hopefully, my TA will decrease too!
