I just got my Taylor 2006 test kit, and have started my first SLAM.
With 50 ppm of CYA, I am maintaining a 20 ppm FC.
Following the directions, after adding in the DPD powder and stirring, I start titrating in the drops of reagent, and reach\
the point where the sample turns clear. I reach for the CC test reagent, and notice that the sample has turned ever so
slightly pink, as if it were bouncing back a little. Is this normal?
Do I keep titrating stirring, and waiting, or is this normal? From the instructions I thought the color change to clear was the indicator.
The pink color is very slight.
CH 180 ppm
CC 0 ppm
FC 10 ppm
