    1st test w/TF-100

    I told Duraleigh that I would post results and here they are:

    FC=6.5
    CC=0.0
    TC=6.5
    TA=120
    PH=7.5
    CH=300
    CYA=80
    Salt=3000

    I suppose the only number I really have to address is TA and get my salt up to 3300-3400. Thoughts?

    With a SWG and waterfall, your PH will always tend to rise. Keep that knocked down to the low end and that in turn will lower your TA.

    Should I put some MA in to knock down the PH and then turn on waterfall? We rarely use the waterfall as it's so loud.

    Those are pretty good numbers. I would lower TA using the aeration/acid method in Pool School down to around 70 for an SWG pool. That may help your pH rise go a little slower.

    I think you are asking about using the waterfall to provide the aeration necessary to lower the TA by acid/aeration......that would be a perfect use. Read that lowering TA article carefully. It works fine but can be a bit confusing at first and it will take a little time.

    I think if the SWG was producing chlorine I might just leave the salt alone......either way is OK.

    With those good numbers, I assume you water is clear....correct?

    Re: 1st test w/TF-100

    Pool Math has me using 59oz of MA to get to a target of 7.2 PH. I think I'll do that and then turn on the waterfall for a few hours and check later on.

    Yes, I've read the article a few times and have actually used the waterfall before to get the PH up a little after using acid when I was using the test strips before the TF-100 arrived.

    Water is crystal clear, have never seen it so clear since finding this site. Thanks again Dave for your prudence.

    FC-strong 5
    ph-7.1
    TA-80
    CYA-70
    Salt-3400
    SWG-70%

    Running aerator for a good portion of tonight into the day to push up PH. I think I'm done with fiddling around with the TA. I really don't want to go any lower. Going to dial in my SWG now as I've been trying out different setting %'s and had to boost it two days ago with some liquid chlorine as I had it turned down to 50% for a day and a half and lost some FC that day. Next few days I'm set on dialing that in and will report back with new solid workable reading that hopefully will be steady.
