The CC of .5 is okay but we'd rather have it at zero.

From here on you test daily for FC, CC, and pH. You add enough bleach to keep the FC between 3 and 6 ppm. This is based on your reported CYA of 40-something. In your pool, 1/2 gallon of 6% bleach will add approximately 5 ppm of FC. You should be okay with adding 1 quart of 6% bleach every evening, depending on the swimmer load that day. Test the water in the evening. It's going to be a little bit of trial and error and we want to err on the high side. You will soon get to know your pool and develop a 'feel' for what it needs.
Okay, my evening test result after adding baking soda and borax are FC 4.0, CC 0, TA 90, PH 7.3 Cya 60. I am going to add a quart of 6% bleach. Do I need to add more Borax and/or baking soda? Thanks
