Does your CYA level affect chlorine production? I usually run my CYA around 50-60 during the summer.Last month I checked and it was 40.I didn't adjust sense it was close to closing.I noticed this week in the process of closing for the season when I super chlorinated it seemed to not increase chlorine like it should have.
 
No, CYA level should not affect SWG production. However, it does affect FC UV extinction. So the lower the CYA, the faster the sun will burn off FC.
