    Purhcased TF-100, and here's my results (Please help)

    New home purchased came with in ground pool and learning everything from here about a week ago. I just opened the pool today and put 3.8lb of D.E in the skimmer after backwashing.

    10,000 Gallons Vinyl Liner

    FC = 1
    CC = 1.5
    PH = 7.8
    CH = 50

    I was not able to get any results for TA and CYA

    TA = I tested 3 times, 2 drops of 007, 5 drops of 008, and over 30 drops of 009 still didn't change color, why is that?

    CYA = tested 4 times, the tube was clear and I could see the black dot even the whole tube was filled with water.


    All test were done with the TF-100 & Speed stir that was recommended here


    At this point, what chemicals should I add to the pool?

    You need to get your CYA up otherwise you will continue to loose all your FC. CYA = Cyanuric Acid can be bought in powder or liquid. Sometimes it is sold as pool conditioner.
    I finally got my CYA to 30 and now am adding about 1/3 gal of bleach a day and the pool is balanced,, using the TF-100 and pool math,, and help from the experts on this board.
    In-ground block / vinyl liner 33' x 22' x 5',, approx 25k gals
    Cartridge Filter
    Floor drains, 2 skimmers, 3 return lines (2" plumbing ultra-flex PVC)
