Does anyone know how to get the CSI to log so I can track it? When I enter new logs it is not an option. I have to open the CSI "tab" and enter some additional data to see what the value is, but it never gives me an option to log it. I have selected to track CSI in the settings, but not borates or water temperature. Must I track these as well to allow logging of CSI? I don't use borates.
