    Rainbow/Pentair CYA Test

    Anyone have the instructions, and sample size vs reagent amount, for that test? (plunger type - kit #79)

    Seems to me it wants 18.5 ml water to get to the first line, and from there it wants 19.5 ml reagent, which is weird.

    Thanks,

    Thanks,

    I found it, FWIW:

    "1. Rinse and fill CYA cylinder to "A" mark with water to be tested;

    2. Add R-0013 to "B" mark. Move stick up and down to mix for 30 seconds. Wait 2 minutes. Read before 5 minutes.

    3. Raise test stick, then slowly lower until black dot on test stick just disappears when viewed from top.

    4. Read test stick at liquid level. Record as parts per million (ppm) cyanuric acid."
