The Hydro Life filter cartridge #2063 says, "Contaminants addressed include bacteria, heavy metals, hydrogen sulfide, lime/scale, chlorine, VOC's, taste, and odor". I note it says "Contaminants addressed" so I'm not sure they are saying it effectively removes CaCO3 or just gives it the Ole College Try. I'm with Grumpy, I think a water softener is needed.
