Reading in Pool School, ABCs of Pool chemistry, "If you have a SWG or very high levels of direct sunlight, CYA is typically kept between 70 and 80." But when I look at the Chlorine/CYA chart 70 and up have an asterisk and say not recommended.
My pool is in direct sunlight all day long so I'm thinking i want to be in the 70-80 range for CYA, does this sound right? Am I misreading the Chlorine/CYA chart?
