I have Hayward Aqua Rite, and the reading on it and the reading from my pool store/test strips don't match. My system says salt is at 2100 sometimes. After a day or so, it drops to 1400 and the inspect cell light and check salt light are solid. I know this means nothing is generating. I can recalibrate and it stays okay for about 24 hours before the lights start flashing and eventually go solid again. I am battling some start up algae and really need to be producing as much chlorine as possible. Stips/store test show salt at 3400-3600. Why is the Aqua Rite off by so much. We have already cleaned the cell (took 3 acid washes), and I have recalibrated a couple of times. Help! My pool's chlorine level is barely existent.
