Already have questions. After the install the low salt light was on even though I tested it at 3400. The installers recommended adding some more salt so I added one bag and hours later the red light was still on. Then I added the second bag and an hour later the low salt light went off. I check and my chlorine levels were up from 7 to 8.4. so it was working. I just need to wait for the levels to come down closer to 4ppm. What to do about the low salt even though my test conflicts. Now testing at 3900ppm slat. Any advice greatly appreciated....
