I installed a CPSC16 last weekend. It is rated for 20K gallons; my pool is 11K. I've been running it at 70% for three days and the FC is still below 1%. Water is perfectly clear, but it seems it should be making more chlorine. Here's the rest. The salt calculator said said I needed a bit over 300 lbs of salt. I added 240 and when I tested, it showed 8200 ppm (I need 3500). The Compupool display showed 7200. The next day, it dropped to 5400 and the Over Salt light went out. Today, it was back to 7000. The instructions said it would work with a high salt level, but I'm wondering if the output is much lower. Suggestions, anyone?? I added the salt 5 days ago, so it should be dissolved.
