    Lowering TA

    Down to the "fine-tuning" on my now clear, clean pool thanks to all you helpful folks! Bringing my TA down from 120ish to around 70. Using MA to lower the Ph to about 7.3 when the Ph gets to about 7.8. I have 6 returns turned up breaking the surface very well and two deck jets running. (plus the SWG at about 20% going 24 hours a day). I now have it down to 90ish (TA) with the help of some very welcome rain the past week. My question(s) are,
    Am I being to cautious in the slow Ph moves with MA? AND...what is the Ph of rain? Just mostly curious about the rain Ph as I do know that the physical action of the rain raises the Ph. Plus, 2 inches of rain is not much considering the volumn of the pool.
    Thanks in advance for your help. You guys have really made this fun for me again!!!

    It sounds like you are doing just fine. Taking your time about it is a good approach.
