getting ready to close in a couple of weeks and just got back from a week long trip. Tested water and all numbers are in line except FC, which was 8 (weather has cooled a bunch and hasn't been a lot of sun) so I lowered the IC40 a little but my salt level showed 2450 on my easy touch and when I tested it with my Taylor kit it was 3600. The cell will be turned off below 2900 right? What do I do?
