So you are adding the powder and then the sample gets darker pink as you add the drops of reagent? How much powder are you adding? You may not be adding enough powder and that is why the sample gets more pink.
Now this seems counter to what you previously reported. The FC test should not "flash" a color, it should steadily lighten and go clear and then you do the CC portion.I agree Kris. Go Mountaineers! My FC test flashes like the PH test, but if it turns pink again I add another drop.
