    My first TF100 numbers

    FC: 3.0
    CC: <0.5 (0.2?) There is a hint of pink, one drop get rid of it completely.
    TC: 3.2
    PH: 7.2
    TA: 80
    CH: 180
    CYA: 30

    New home and first pool. Water is 2 weeks fresh.
    Have been using trichor to build up CYA. From now on I am going to
    switch to liquid chlorine.

    The previous owner has been dumping trichor over the years.
    CYA is way of the chart. Drain 2/3 water and CYA is still off the chart.
    I don't know how many times I need to half drain the water to get CYA
    to acceptable level. Feel guilty of wasting so many water. So I drain the
    whole pool and refill it.

    Of course, the pool starts to leak 1 inch a day. I have some one to fix it.
    I believe the hole on the vinyl is there before the drain. The drain separates
    the vinyl from the wall so it leaks much faster. Now every thing is good.

    I have been using the OTO test to watch the chlorine level. Just get
    the TF100 kit. This is my first time to use the kit. I can see why the DPD
    test is better. Changing color from red to blue is much easier to read than
    the yellow scale.

    The water is very clear.

    Those numbers look good. I'd probably up the FC a little even though it's within the recommended range for a CYA level of 30.

    Welcome!

    And not to worry about CC until it's more than one drop can clear completely.

    Ah, You are right. I confused that with the TA test I did right after it.
