My Intellichlor IC40 is showing an incorrect salt level. It is just slightly over 1 year old. It was showing low, but my Taylor drop test showed 3600ppm. I added 1 bag of salt to see what it would do and it got me over the threshold for low salt for a bit (a few days), but is now showing very low salt again at 2550ppm. My tests come up with 4200ppm. Below is where my pool was sitting yesterday for all other tests including salt. Any ideas?
