    First test.... now what

    Okay, so finally I have the numbers from my first test using the TF-100 kit. This is for a SWG.

    Water temp: 83
    Salt: 3000ppm
    FC: .5
    CC: .5
    pH: 8.2
    T/A: 60
    CH: 210
    CYA: Filled all the way and could still see the black dot. Is the water in the test bottle supposed to get cloudy?

    It' obvious my chlorine is too low, right. I've been running the filter and SWG only about 4 hours per day, at 45%. I ran the boost overnight, and just this morning bumped the percentage to 60%.

    What next? I'm concerned about the CYA - either I didn't test right, or it's very low.

    I would lower the PH and also start to put in CYA. How does the water look?

    Water still has a green tint to it in the deep end. Shallow end is looking a lot better.

    Do I need to add something to raise the chlorine?

    Yep, your going to have to shock. It's not a freshly filled pool? If not your going need to read Pool School in my signature and read about shocking your pool. Your just taxing your SWG, so bleach is going to be your friend!

    When CYA is zero the water sample won't get cloudy and you will always be able to see the dot. So your results are normal, and indicate that CYA is either zero, or too low for the test to measure.
