Calcite

Generally for residential applications people use granular calcite (calcium carbonate) in an up-flow contactor. You use granular material to get good hydraulic flow and to get enough surface area to actually dissolve the mineral. If you use too fine a granule they glue themselves together in a mass and then the system won't work. Firms like Kinetico or Culligan (just to name some common ones) are your best bet as they have pre-engineered systems that will do this. The ability of your water to dissolve the mineral will be based on temperature, time and "aggressiveness" meaning how corrosive the water is.
