Once I have my chlorine test solution clear ( FC test ), I add the 5 drops of DPD reagent. (All while SpeedStir is active). The solution remains clear.
If I go do another test, say PH, and the chlorine tests stay still ( NO SpeedStir active). The solution turns a pale pink.
If I turn the SpeedStir back on the solution stays pink, and If I add a drop of FAS-DPD reagent the solution clears up.
Letting solution sit again, it will eventually turn a very pale pink again.
Is my CC a bit more than it seems when I see no color change after adding the initial drops, or is my testing method flawed in some way?
Thanks,
Steve
