I have a zodiac duo clear 60 saltwater chlorine generator and I have had this add salt light on for the past few days, I added 2 bags of salt and my actual reading is getting too high now but the alarm still won’t reset. I am not sure what’s going bad in the generator, don’t know if the cartridge is on it’s last leg or something else is the problem. My FC is beginning to drop. Any way I can fix this or a short term solution so that I don’t get a I’ll blown algae. Thanks
