Hello everyone--love this forum! My pool is 6 years old, and the saltwater generator (Zodiac DuoClear--which is no longer making this SWG) always worked fine. This year it has not made any chlorine, even though all of the lights are on as if it is working. According to pool store readings, I've balanced the water and added enough salt. The water temp is 80 degrees. They've had me add "shock" regularly for the past three weeks because of low chlorine readings.

Do I need a new SWG cell ($700)? I saw that they only last 5 yrs on average, but my pool is open only 3 months/year, so I thought I'd get much longer out of it. Help, please--I am so confused and no one I talk to (even at store) seems to know what to tell me.

Here are most recent numbers:

Free Chlorine: .11 ppm
Total Chlorine: .11 ppm
Combined Chlorine: 0 ppm
pH: 7.4
Harness: 187 ppm
Alkalinity: 78 ppm
Cyanuric Acid: 37 ppm
Copper: .9 ppm
Iron: .1 ppm
Borate: .1 ppm
Salt: 4310 ppm

Thank you for any insight you can provide, especially about whether to buy new cell when I don't even know how to determine if that is the problem. Cindy in PA
