Hello,
My generator is a Jandy Truclear 11k which recommends 30-50 ppm per the operation manual. I'm about at 20ppm right now and planned to build to about 40ppm to be in line with the product manual. I have a 13k gallon pool which was just completed in the last few months.
I was just curious about the recommendation from the CYA/Chlorine charts published on this site, which states 70ppm minimum. I'm just trying to understand why the recommendations here are much higher than the Jandy literature. At 20ppm CYA i've been saturated at about 5ppm FC with the generator running at 50%(10 hr per day). Since this is a new pool i'm not sure what the chlorine load is going to be throughout summer, but if I am able to maintain a high FC at a low CYA (in relation to the TFP recommendations) is there some other phenomenon occurring in the water treatment that leads to a higher CYA requirement for SWCG's?
