FC 9.0 (overdid it with chlorine last night, generally do 7.0)
Yields CSI of +0.11
Water looks perfect, only problem is that I have been trying to maintain the pH at 7.2 to drive the CSI slightly negative. It just bounces right back to 7.5-7.8, and I feel like I am spending a fortune on MA. Also been adding baking soda the last week, and have gotten the TA up from 60 to 70. Its a 2.5 month old Pebble Fina dark colored finish, paranoid about calcium scaling since I am on well water. Anything I should be worried about?
