How high is normal to let you ppm get before u start getting spots? I'm In a hard water area under the tap it's at 295 I started using the system 2 weeks ago & to start off it was at 0.3 & in 2 weeks it's gone to 0.8.. Not having any problems yet but not sure how often I need to change it really.. Got a very busy week next week need to keep on top of it. Thanks in adv
