Is there a test similar to the OCLT except you determine the chlorine demand during the day? I've thought about this. If I can determine the chlorine demand during the day, I could use that information to set my SWCG.
Occasionally, I run the OCLT just to see if everything is running right. I did this again on Sunday night. In the evening, the FC was 10.0 ppm. The next morning it was 9.5 ppm. Since my FC was still plenty high, I decided to keep the SWCG shut off for the day and retest the next evening. My resulting FC was 7.5 ppm. I lost 2 ppm during the day. Interesting enough, my SWCG is set to produce 1.8 ppm per day. My FC for the last few weeks has been steady at around 10 ppm. It seems that I confirmed that my SWCG is set for the right percentage to produce what my pool needs daily.
