    Most Recent Numbers

    Here are my numbers for this evening. I feel more comfortable now that my CH numbers are correct after talking to some others on the board. I am still waiting for my FC numbers to drop more to get an accurate reading on PH before adding any acid.

    Other than that, please feel free to send some comments and/or reccomendations.

    Water is super clear and looking good!!!


    FC - 16
    CC - 0.5
    TC - 16.5
    PH - 8.0
    TA - 110
    CH - 390
    CYA - 70
    Salt (SWG) - 3500
    Salt (Strips) - 3460
    Borates - 30
    Temp - 67

    I think your pH test is accurate enough and I would lower it to 7.4.

    It will tend to rise anyway and, even after your FC drops, I think you will find the pH test has reported accurately. If so (and there is not too much doubt in my mind), then your pH is too high. you never want pH in the 8's and 7.4 is about perfect.

    With FC around 15 the PH will probably read a little higher than actual, by 0.1 or maybe 0.2. Also, as the FC level falls the PH will also fall a bit. It wouldn't hurt to lower PH just a little, but I wouldn't lower it too much till the FC level has come down more.

    I would just drop it to 7.6 since you have a SWG.

    Thanks for the information guys. I will add some acid and then check it again. I am guessing that my FC will be <10 within a few more days based on the rate that it has been dropping. As you know waterbear... not much sun for us yesterday and possibly today.

    Well I am off to make another refill order with Dave. LOL I am having so much fun with this now that things are looking better and I am understanding them better.
