What does everyone set their SWG at while having active swimmers? I’m pretty dialed in now just trying to figure this out. CYA is at 30 since we live in Chicago and I have an autocover which is almost always on. Only time sun sees the pool is swimming and days after shock or random off gassing. I tried 80% before and it seemed to work well. The day was 83 with full sun and it appeared to keep up plenty with the bather load. I believe it never went below 4PPM chlorine that day. Suggestions?
 
80% seems high for your setup. I run 24/7 similar size pool, full sun, no cover, 54 CYA, and run the ic40 at 17%. I’m still backing it down slowly because I’m still around 5 ppm fc and want to be closer to mid 4.
