I'm seeing an issue where my FC is much higher than my TC. PH levels are good and CYA is around 35. However, FC is around 10 and TC is around 2.
This was tested with 2 different brand of strips (I know...) and chemistry is not with BBB. Chlorine is typically added via 3" puck (calcium-based if I recall correctly) in the skimmer. Pool details are in sig. I'm trying to understand how FC can be higher than TC and what I should do about it.
