    All fine. It wouldn't hurt to use borax to raise your pH, however. The by-products of the oxidation process tend to be 'nicer' at a higher pH level.

    CYA It was less than the 100 mark (was not sure what number to put)
    This indicates that your CYA level is MORE than 100 ppm. That's consistent with the theory that you had high CYA, that was partially metabolized by bacteria to form ammonia.

    You'll eventually need to retest, using a 50:50 dilution of pool water with DISTILLED water, and multiply the result x2. You must use DISTILLED water and not "spring" water or any of the other variants: http://www.walmart.com/ip/10315382

    Thank you for looking at my numbers. What exactly should I do now. I've been adding bleach everyday until I got the test kit and the numbers needed to determine the problem. Will I be adding bleach everyday from now on or should I be doing something else? I guess I remain a little confused about the next step.

    If it were me, I'd retest the cya using the diluting method 1st. You may need to drain. You'll just be wasting bleach if you need to drain. Good testing aways gives you good answers about what to do next.

    Yes, we need to verify that your CYA is really as high as it appears, before we can really proceed. Watch the CYA video again.

    And, take a look at these Taylor images:

    I tested CYA again and maybe I did do something wrong the first time. I really watched until I was SURE I didn't see the black dot and now it registers about 80. Does that help? Hang in there with me-please!

    80 is pretty high but workable. This late in the season, draining might not be worth it. Its up to you. Check the best guess chart for the amount of bleach youll need at 80 cya (24 FC I think) to stay at shock levels.

    I have looked at that chart and have no idea what it means. I don't mean to sound stupid here, but am I missing something? Where does the chart indicate how much I need to add? Is there anyone who can explain this to me?
