    Ph Slightly Low

    Okay, pool is fully up and running and I must say thanks to Texas Splash for the initial instruction.

    Here are my results as of last night:

    FC - 4
    CC - 0
    CYA - 30
    TA - 120
    Ph - 7.4

    I have 2 questions:
    1) Will the CYA fluctuate and need to be adjusted periodically?
    2) Should I be increasing the Ph slightly to get up to about 7.6?

    AGain, thank you to everyone for the assistance. Let me assure anyone out there that the initial water testing can seem difficult but it is so ridiculously easy once you do it a few times.

    Re: Ph Slightly Low

    Thanks for the comments. CYA will not rise unless you want it to or add a stabilizer product. It will drop when there is a significant amount of water exchange due ot heavy rains, lots of backwashing, or lots of splashout. A little gets used each month (about 3-5 ppm). So it's good to check it every so often just to make sure you have good protection to the pool and FC from the sun. As for your pH, it is slightly low sure, but should be okay and rise fairly quickly because of the elevated TA and aeration caused by swimming and such.

    Hope that helps. If you have any more questions, just give us a shout. Have a great day.
