I have just converted my pool from Bacquacil to Chlorine and am having trouble with getting my FC to 15. I have not added CYA yet. I test at night and early in the morning. It is hot here, 100 degress every day. Pool is in full sun all day. My pool went from cloudy to crystal clear. CC level is 1.0. PH is 7.4. FC at night is ranging between 7 and 9 and in the morning it is between 4 and 6 ppm. I follow pool math on adding more chlorine, but my pool eats it up every night. Am I doing something wrong? It's so hot, I want to swim before summer is over. I started conversion 1.5 weeks ago.
