What is the "normal / typical" level of FC being generated by a salt cell (I have Hayward T-CELL-9) at 100% / Super Chlorinating. Although I have gone through SLAM twice, I continue to experience FC loss (even with CYA of 70-80).
While recognizing my test was not exactly accurate / scientific, I placed (with my thumb to cover) a sample tube and syringe in front of my return to capture the FC level (tube = 2.0, syringe = 2.5). All indicators are within range and my salt level is 3400 ppm. My cell is exactly three years old and being used 3-4 months a year.
Is this normal?
