Right!


In your suggestion you are mixing equal parts pool water and distilled water but doubling the result when poured over the black dot till it disappears. Would that mean that distilled water is nearly the same thing as R-0013 except that it is twice as clear? By the book, I never have to buy R-0013 again if I use your procedure correct?
Not quite right!
To measure CYA higher than 100 (max of test), one would dilute the pool water sample with water that contains no CYA. Perform the CYA test using equal parts diluted pool water and R-0013. Read the CYA in the diluted sample the multiply by the dilution factor(2 for a 1 part pool water + 1 part distilled).
