I'm still getting the hang of doing the test with the tf test kit. I've learned how to get consistent drop sizes with the reagent. And I use enough dpd powder. And I use 5 drops of r0003 to test for CC. But here's the situation I'm having now.
Tested the water this morning and got FC - 3.5. CC - 1. TC - 4.5
Tested two more times immediately after the first test and both times got, FC - 4.5. CC - 0. TC - 4.5.
It has been like this since I started testing this year. What am I doing wrong? Is it possible the the r0003 is remaining in the graduated cylinder from the first test and causing me to effectively test for the TC in subsequent tests?
I also just got a speed stir so I don't imagine that I'm swirling the test wrong since it's done automatically now.
Thanks for any input you all have!!
