Based on my readings at TFP, and the test kits, when there are measurable levels of combined chlorine, it means that there is likely some bad stuff in the pool that the FC level is not taking care of. Since using the TFP method for 3-4 years, life is pretty simple, my pool water is clear, no algae, FC level where I want it, and usually no measurable combined chlorine.
As I understand it, combined chlorine means there are chloramines present, which is bad. If that is correct, then why are municipal water districts using chloramine as a disinfectant, instead of chlorine?
Thanks.
