I have a AquaBlue SWG installed in my pool and have recently come up with a strange problem
FC content goes skyrocketing, well above 3ppm that is no matter where the adjusting dial is set. Have experimented enough, kept the SWG system off for a couple of days, the FC went to zero but two days after running SWG again the FC went over 3ppm.
Anyone have any idea of what could be wrong?
The system is two years old, cell have been cleaned ok, salt level is 3500ppm, pH 7.2
