I'm not clear on how you are doing the test.

After you add the two scoops of powder and the sample turns pink, you add drops of R-0871 until it turns colorless. Then you multiply the number of drops by 0.5 for a 10ml sample. This is your FC. (You wrote -- fc ppm = amount of drops to turn the water clear / 2. That is the part that wasn't clear to me about what you meant.)

Then, you add 5 drops of the R-0003 and then add drops of R-0871 one a time until it turns clear. Then, again, you multiply the number of drops by 0.5 for a 10ml sample. This is your CC.

Is this the way you are doing it? What does the / 2 part mean?

Please clarify for me and if you did not perform the test in this manner, try again and repost with corrected numbers.

If the numbers you posted are correct, it looks unlikely that you will be able to swim today. You don't want to swim in water that has a CC reading higher than 0.5 and I also wouldn't swim if the FC was higher than 10ppm. (Even then, you would need to wear old swimsuits that you wouldn't be upset if it faded some.)
