I'm looking for advice on a problem I'm having with my AquaPure 1400 Chlorine Generator.
I'm wondering why, over time, my salinity level keeps RISING (now at 4,000). Over 4,000 and the system ceases to generate chlorine. About a year ago, I had the same problem, but a test of the water at my local pool store indicated that the calibration of my generator was off by about 700 mg/l. I recalibrated the generator (to 2,800) and all was well throughout the last season, although it did continue to "creep" up slowly. I run my pool year-round and am diligent about maintaining chlorine, pH, and total alkalinity levels. This morning, I took a sample to my local pool store and they confirmed the 4,000 reading. I am at a loss as to why the level continues to rise?
Does it have something to do with the fact that my "make-up" water is softened? It was designed this way because our raw water is extremely high in calcium and causes significant scaling. Also, I replaced a failed salinity/flow/temperature sensor a couple of months ago.
Any thoughts and/or ideas would be appreciated.
