I have been having a little trouble with my SWG settings, and I have addressed those issues in that forum. My FC is at 7.5 this afternoon, and my CC is at 0.5, This morning my CC showed 0, crystal clear water. Yesterday I did two chlorine tests, and one time CC was 0 and the other time it was 0.5. What am I doing wrong, or am I just over thinking this. BTW my CYA is 70.
