I've been perusing the CYA/Chlorine charts and noticed that the ideal CYA level for a SWG pool is 70-80 CYA. Obviously this has an impact on a higher level of FC necessary to sanitise the pool (ie- for CYA level of 70 it suggests a targeted FC of 5. My question is based around the tolerance of solar pool blankets. The manufacturer of my solar pool blanket recommends an FC less than 3. I basically have my pool covered whenever it is not being used. Is the manufacturer being overly conservative and should I just go run with the suggested CYA/Chlorine levels as above or go with a lower CYA level?
