Taylor Test kit 2006c

Actually, if one scoop turns the sample pink, then you don't need to use two. I always just use one scoop.

it is a tritreation test. DPD is merely the indicator. The titrant will react with the FC in the water (or the CC if you are doint that part) and once the chlorine has reacted with the titrant then it is no longer available to react with the DPD and turn it pink. sometimes half a scoop is all that is needed witha really fresh DPD powder if the chlorine levels are not too high!

Makes sense.
