    Concerning pH, I think I know the answer.

    Been noticing a slight upward trend in my pH levels over the last couple of weeks. I'm guessing it's due to heat. My pH used to live in the 7.5-7.6 range but lately it's been creeping up a bit. Today, I would say it's just under 7.8 but not quite there. My other levels are below.

    FC - 5.5
    CC - .5 (heavy swimmer load today)
    TA - 80
    CYA - 70
    Salt - 3900 (high and it's my fault after a bad cell issue, it's slowly coming back down...fun)

    Should I wait a little longer to add some muratic acid and bump the pH down or go ahead and do it now? If I need to do it now, that leads me to my next question. I haven't had the need to lower or raise pH yet and I know it's done with acid or borax depending on the direction. Can I find muratic acid at my local WalMart or am I going to have to go to the pool store or some other store to find it?

    Looks like 7.2 actually might be lower than I should go after looking at the numbers in pool school again? Maybe more like 7.5 would be ideal since I'm not seeing dramatic rises in the pH level?

    7.5 will be fine. You can find muriatic acid at most hardware stores.
