I don't think the CC numbers are due to being off by a decimal point. Even a CC reading of .52 or .26 don't make sense or if you go the other way to 52 or 26 either.

To clarify how to run the CC test,
You use the same sample as you have been using to test for FC. You add 5 drops of R-0003. If the sample turns pink, you have some CC. You then add drops of R-0871, one drop at a time, just as before, swirling to mix after each drop, until the sample turns clear. Then, multiply the number of drops by 0.5 (if you used a 10mL water sample) or by 0.2 (if you used a 25 mL water sample.) That would give you your CC reading.

(IF the sample does NOT turn pink, then your CC reading is 0 which is ideal!)

(By the way, best to use the 10ml water sample as that will conserve your reagents.)
