Hi all, when using a Taylor K2006 FAS DPD chlorine test, how long after adding the 5 drops of R-0003 should I wait before either accepting no colour change or seeing a shade of pink?
I.e if there is CC present, will the water change to a shade of pink as soon as the drops hit the water or should you wait for a few seconds after all 5 drops have been added (5/10/15/more?)?
I often see no colour change immediately after adding the 5 drops but after 15/20 seconds or so a shade of pink sometimes creeps in.
Thanks!
