When testing for cc in my bucket test, I got a yellow result last night AND this morning immediately after adding the r-0003 reagent. I suspect this indicates that my cc is off-the-charts high. So I experimented a little this morning... I went ahead and started adding r-0871. Each drop swirled pink before the sample turned yellow again... This happened until about drop 40 when the sample finally stayed pink. I kept adding reagent until i hit drop 80, but the sample was still pink. So, either my bucket test has cc over 40 ppm, or something else is going on here. FC was 6.0 btw.
