This pool is becoming a pain in the rear. I am on day 10 of shocking pool. I am no longer swamp green but a deep cloudy blue. My problem is my FC never seems to come down. So I don't think I am adding enough bleach during the day. I was using the test kit from Walmart but it only goes to 5, now using the test strips and those keep reading at 10 Fc. The reading never changes, I test about 3 times a day. 11am-3:30Pm-12am. I vacuum once a day before I go to work. With my cya low shouldn't I be losing clorine. Since I can't see bottom of pool I know the test can't be right. I ordered the tf100 today. What should I do until then Since I'm most likely not getting correct reading? When pool guys repaired my filter they used the zeote sand. Supposed to be better but who knows. I have next dose of cya dissolving in a sock in the skimmer. Since reading never changes I add 2 gallons of 8.5% bleach a day. Once at 11am and then at 4pm.
