Here are the measurements I have so far:

CYA: 63
pH: 7.2
FC: 4.6
CC: ????

I followed the instructions exactly. The water became clear on drop 4 which would equal .8 ppm. I left the water in the comparator tube as I wrote down my results and put stuff away. The water in the tube turned pink again. So, I added more titrate and swirled, swirled, swirled until it was clear again at an additional 2 drops. Once again, as it sat in the tube for a minute it turned pink. I did this over and over. After 14 drops I gave up because something has to be wrong. It turns clear, I put it down for a minute, then it turns pink again. I cannot find anywhere that tells me if this is normal. Please help!
