    Salt level discrepancy!

    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?

    First, check that the cell is not scaled up. Reading lower than normal is a sign of a dirty cell (or failing, but this is pretty new for that to be the problem).

    Has it turned off for low salt? My Circupool is supposed to shut down at 2500 and below, but would give me a warning before that.

    Shouldn't be scaly cause I cleaned it in August and it wasn't scaly then either. It is not off it still has lights on.

    Re: Salt level discrepancy!

    I had a similar problem with my IC40 persistently reading low levels of salt. Even though I didn't see any scale on the cells, there must have been some buildup on the salt sensor. Cleaning the cell with approx 60/40 H20/muriatic acid (29%) resolved the problem.

    My salt readings have been pretty stable at around 3600-3800 ppm for the last 4 months. Previously, the sensor was reading 2700 ppm. The reason my salt is so high is that I had added a couple bags of salt before discovering the real issue.

    When you cleaned the cell, did you fill it high enough to cover the sensor?

    I Ryan it up over the plates a little bit. Don't really remember if I'd went over the sensor.
