There are two sets of directions for the k-1579. One for Bleach solution 10-1000 ppm and the back of the card is for a more potent bleach solution of 0.1% - 15%. The video is confusing because the demonstration uses a 0.5ml sample called for when testing a more potent solution but follows the steps for a less potent solution. For the .1% - 15% test solutions R-0636 and R-0700 are not necessary.
If no test strip is required how to you determine the percentage?
