Can someone tell me the average daily loss of fc. It seems my loss each day goes down 2 to 3 ppm. My pool is in full sunlight all day & temp is now 90 or higher. I usually add more bleach than the calculator suggest I add,but don't want fc to drop below my target of 6. Thanks for all advice. FC 6,ta 80,ch 50,cya 40/50,cc 0,ph 7.7
