I am curious about all of the negative numbers. Should that be read as zero, ignored, or is there significance to them?
For example, my result was -0.2ppm Iodine. My other Triton tests typically show around 0.01ppm.
I've also been trying to control Si and have typically been high measuring around 0.270 ppm from Triton last month and the new ICP has -0.16 ppm. 0.16 ppm would sound about right given some bigger water changes I did between the tests but not sure how to read the negative.
