Towney, Did you ever figure out what was causing your issues? I am having the exact same thing happened to me and wondered what your solution was.When I try Ping's fix I get a H.H Salinity GPL showing on the panel. Unable to move it up or down. Mine is the 1400 AquaPure Apurem and only 4 months old. Any ideas on my code 145 High Salt 10400 reading? Could PH high or low cause this for before error pool was registering 2800 salinity and for what it's worth we have had a tremendous amount of rain over the past week here.
