Quick question, My pool is looking great again this year thanks to BBB method. But....I added 2 182 oz. of 6% bleach and 2 96oz. 6% bleach night before last. Runnubg a 70 CYA level. FC level was at 20 PPM early yesterday morning. We are under accessive heat warnings here and have been a lot the last couple of weeks. Ok...I added approx. 2" of new water last evening and then did FC test again after the sun went down and it read 8.5 PPM. Is that possible? I am going to go get more bleach today...just have been using a LOT lately. Water temp has been staying between 92 and 94 for the last 2 weeks.
