Thank you to everyone for sharing their knowledge and experiences here at trouble free pool. We started to convert from baquacil to chlorine 1 week ago. No baquacil was added for 9 months so I'm assuming it is very low. Using the pool calculator I have been adding the recomended amount of chlorine each evening to reach 15 ppm. Our pool is 23000 gallons and I've been adding about 6 gallons of bleach each day. The pool still has a slight green tint to the deep end. The backwash discharge is starting to look better. So far I have been through about 30 gallons of bleach. FC is still only 1 or 2 in the morning. CC is above 30. My questions are: Is the high CC reading a concearn at this point? Should I hit it harder with the bleach? ( I checked after adding amount recomended by pool calculator, in the evening after brushing, and FC is only about half of the recomended 15 ppm about 20 minutes after adding bleach) Can 78% cal hypo be substiuted for bleach? I'm being burried in bleach jugs
