I just realized I never turned on the setting to share the pool math logs on my profile. Fixed that. I'll note that my CYA levels are complete guesses based on relative cloudiness, since it's too low to get a real reading.
Thanks for your help! I had wrongly assumed that the stabilized chlorine would not show up as free chlorine.Correct. The chlorine will move from reserve chlorine to active chlorine as you need it.
