My sister has a mineral sanitzer that distributes copper and silver to sanitize. They recommend a chlorine level of .5ppm.
The question I have is about CC. I tested her levels and had a FC level of about .5 to 1.0, but then when I tried testing the CC, I was up into numbers of 7.0ppm and stopped testing because the pink was just not going away and did not want to waste any more of my solution. Will these sanitizers throw off the CC levels? I used my TF-100 to test.
