My test from tf says 14 fc. The test with the tablet says 11. My cc in both tests is .5. Cya is 40. My pool finally went from green to murky blue on Wednesday. It took from june 25 to july 5 to go from swamp to murky blue. No chemicals or pump before june 25. I was using the tablets from last Tuesday until Friday when the refills from TF came. I had to shut off the pump for 2 hours yesterday and I went back to murky green during that time. This morning its back to murky blue. Which dpd should I be trusting?
