I have a Hayward SWG control that is displaying 2500ppm and is indicating "Check Salt" and "Check Cell". When I test the salt level with the Taylor test kit, I get 3200 ppm. The sanitizer level is dropping (down to 1-2 ppm the last two tests from a previous level of about 5), but I don't want to add too much salt. The water is beginning to look like it might be clouding. It's a 30,000 gal in-ground vinyl pool. Any suggestions?
