    Dialing in SWG and First tests with TF=100

    Friday evening results
    FC - 7.5
    CC - 0.5
    TA - 100
    CH - 220
    pH - Over 8.2 added 77 oz 14% MA retest over 8.2 added another 64 oz MA finally got to 7.5
    CYA 70, 70, 70, 75ish, 70, 70, 80 I'm calling it 70
    Salt - 4600 Ok, blew it here, but SWG is happy. No High Salt alarm

    Lowered SWG output 10% Friday night.

    Sunday Evening
    FC - 7
    CC -0.5
    PH - Over 8.2 added 36 oz 31% MA to get 7.5 pH
    TA - 100

    Lowered SWG 20% Sunday Evening

    Monday Evening
    FC - 6.5
    CC - 0
    pH - 7.8 Added 32 oz 31% MA to get pH to just under 7.0 to lower TA
    TA - 100

    I'm letting the SWG do the aeration. It and the new plaster have been doing a fine job of it so far.

    Since I work out of town 4 days a week I won't be able to do any testing until Friday night and the wife refuses to learn to test the water, I've pre measured 3 bottles of 24 oz of 31% MA to add 1 daily until I get home in hope that the pH won't climb off scale again.

    My plan is to continue lowering SWG output to get to a 5.0 FC at the end of the day and to work on lowering TA to get it in the 60 to 80 range.

    Am I on the right track?

    Thanks in advance, you guys/gals are awesome.

    Yep, you are doing great!

    One thing you probably know already, you want to test the FC level late in the day after a sunny day. Testing on cloudy/rainy days will give results that have higher FC levels than sunny days, and it is the sunny days you need to adjust the output to handle.

    Cloudy in Las Vegas. Not very often.

    Thanks for the reassurance. I'm still a nooby.

    Might be a newbie, but that's good work, JB.
