I had been using pucks but after reading here I removed them and went to 8.25% bleach until my k-2006 arrived today. My water is the tiniest bit hazy compared to a week ago. No smell or sliminess.
When testing FC the water never turned pink. I then added R-003 and there was the very slightest pink coloration, almost unnoticeable. I used the 25ml sample for testing. I have no idea what the note in the instructions is referring to by the" Note: 1 drop=.2ppm use 25ml sample or with the 1 drop=.5ppm, use 10 ml sample." Perhaps I did or read the test wrong for FC and CC? So question is what next?
