Glad you got your pH up. 7.4 is a good level. TA is also ok. I still think there is a problem with your chlorine numbers. What type of test kit are you using? Can you explain the procedure you are using to get the cl readings? Something is not right or else you have a big problem on your hands if your CC reading really is that high! (Remember FC + CC = TC so if your numbers are right, then you have a CC reading of nearly 15 which is NOT a good thing!! I'm really hoping it is a testing error!
