Starting up the pool for the year and still getting things balanced. I seem to have an issue I don't remeber having in the prior two years. My SWG is off due to very low salt - 2500 ppm on the display. However, the salt test kit is showing 3200 ppm (still a little low as I am working on balancing everything right now). I remember it always reading low when the water temp is low (60 deg currently), but not off by this much. Has anyone else had this issue? Hoping it starts coming up on the unit soon or afraid something might be wrong with the sensor.
