Has anyone plotted FC during the course of the day to see what kind of trend line it is from sun up to sunset?
Also how about cloudy days versus bright sun?
And one more, at the end of the day is there a "coast down" drop in FC at sunset? The reason is I've been doing my testing about 1 hr before sunset and I was wondering if that matters much. I would suspect that as long as it's about the same time each evening that would be OK since adding 1-96 oz jug of Ultra 6% (calculated about 2 ppm FC addition) has kept me at 8-8.5 FC, 0-CC at the end of the day when I test. I've been this way since shocking the pool last week, YEA!. (CYA is ~80 and Full sun all day).
