Hi all, was wondering if anyone has ever seen an aquatrol reading its salt as 1.60 instead of the typical 1200-1800ppm range? All summer my salt has been showing up normally at 1500-1600. Now its reading 1.60 and cant get it to read properly again. Its a T5 replacement cell installed in June of this year. I tried powering it down completely but it didnt help....thanks in advance!
