    Soft Water - Good quality, No Ca or MG
    Temporary Hardness - Ca ions can be boiled out to make it soft
    Permanent Hardness - Cannot be boiled. Try Ion Exchange methods
    2:06 MgHCo3
    5:48 Permanent hardness Is made up of Sulfate Ions (CaSO4^2)
    6:15 Sodium Carbonate - aka “Washing Soda”
    Ion Exchange resins absorb Ca and release H ions, or sodium ions
