This old man needs a little more advice. This time on testing FC. I think I'm doing everything correctly but I'm not getting the expected results.
I fill the tube to 10 ml and add a heaping scoop of the powder and swirl. The water turns pink with the addition of the powder but during the second or two of swirling the water turns sorta milky white. And this is before I add any drops. When I begin adding the drops the water stays milky (or cloudy) then within about 15 drops or so starts turning pink again and stays that way, even up to 40 drops.
What am I doing wrong? And am I looking for the water to go from pink to white (milky, cloudy) or should it go from pink to clear (see through)?
Other info: The water is crystal clear. PH is 7.2. CYA is still high @ over 100.
