Hello,
We purchased the 2006 FAS-DPD test kit to more thoroughly test the pool water. However in comparison to the OTO test or results from Pinch-a-Penny the chlorine test always comes out to about twice as high. Meaning currently Pinch-a-Penny says the total chlorine is at 4ppm. The OTO test comes in between 3 and 5 but the DPD test measures 8ppm. And no matter how the chlorine level varies it always reads about twice as high.
I've tried testing both the 10ml and 25ml methods, purchasing new agents, using a magnetic stirrer, and using only one scoop of powder. Nothing appears to make a difference. All the other tests perfectly align with the Pinch-a-Penny results.
I also tried reaching out to Taylor but they basically treated me like I couldn't count drops. Is there anything I am missing that can be causing these results?
