    1st water test; New Fill; 1st time pool owner

    My very first pool is installed and should be finished filling today.
    Since the water level is now within reach, I did a complete test of it with my new TF-100 kit

    Here are the results; assuming I did everything correctly:

    FC: 0.5
    CC: 1.5
    TC: 2.0
    CH: 50
    TA: 40
    PH: 7.2
    CYA: 0

    The bleach that I bought and will be using is the store brand from Target. Its regular bleach, 121 oz jug and says Active Ingredient Sodium Hypochlorite 8.25%, Other Ingredient 91.75%, Yields 7.86% Available Chlorine-----is that the number I should use in PoolMath (7.86%)?

    Trying to determine what I will need to add to my water once its full and ready.
    Thanks

    Plug 8.25% into Poolmath.

    While you're at Target, pick up some Borax and some Baking Soda to raise pH and TA a little. I'd target 7.4 pH and 70 TA. If you overshoot a little because the pool volume is slightly off, it's no big deal. If you undershoot, it's easy to add more.

    You also need to add 30+ppm of CYA ... you can find the stabilizer/conditioner at Walmart.

    I think I would skip the borax and just raise the TA some with baking soda, pH will generally climb on its own.

    ..and just to be clear, I put the CYA in a sock in the skimmer and leave it alone until its empty, correct?
    If that is right, after its dispersed, how long do I wait until I retest CYA?

    If you leave your pump on 24/7 that is fine. Or hang it in front of the return jet. Give it a few squeezes every so often.

    Once it is dissolved, assume it is active (to determine your FC levels), but do not test for a week.

    Ok, thanks. One more question about PoolMath, since I have 0 CYA, its only computing a "goal" of 1-3ppm FC for me. Is that right? It only because I have no CYA. Should I instead add the correct amount of bleach for a "goal" of 5 FC instead?

    Until the CYA is in the water, just keep the FC up to around 2ppm. As it dissolves, you can raise it up to 5ppm.
