Good morning, I have a one year old pool with all Pentair equipment. Due to cold water I shut down the IC-40 over the winter and just added liquid chlorine as needed.
Now as I start it up I am experiencing pretty wide variations in salt water ppm depending on how I test. My current water temperature is 69 degrees. Prior to testing I cleaned the salt cell per Pentair's instructions.
My Taylor kit is currently showing 5800 ppm. The IC-40 is showing 4350 ppm, but a couple of days ago was showing in the 3800's. I dropped a water sample off at the local pool store and their test showed 3300 ppm. I'm losing confidence in my ability to determine the actual salt ppm. Should I just go with the results of the Taylor Test kit? Thanks!
