I know it seems like a good thing that my FC is not dropping, but I'm just curious if this sounds right.
My pool is in direct sunlight most of the day. I tested FC 3 days ago and it was 9 with CYA at 60. I turned the SWG off because I'm aiming for FC of 5. SWG has not been running for 3 days and my FC today is only showing 8.5. Could the stabilizer just be holding my levels steady that well?
I'm certain that I'm performing the test (with TF-100) correctly and I do not use any other form chlorine. Am I missing something or does this seem normal? Or am I just overthinking this?
