Do yourself a favor and forget the DPD kit and get an FAS-DPD kit. It's easier, more accurate, and can test much higher chlorine levels with an accuracy as great as .2 ppm!

Evan's right--you are just wasting money--and you'll have to get a FAS-DPD test kit sooner or later anyway.

DPD only goes to 15ppm before it bleaches out--looking like you have NO chlorine!
