This Big Blue system uses a 20\" Big Blue cartridge format; Crystal Quest lists system cartridge dimensions as 5\" × 20\" and replacement cartridges as 4-5\/8\" × 20\". The alkalizing cartridge uses calcium carbonate media to help raise pH, alkalize\/ionize, and remineralize water. Depending on the selected configuration, the system can also include SMART filtration and carbon block filtration for additional treatment stages targeting contaminants listed by Crystal Quest. It requires no electricity and no backwashing, making it a practical cartridge-based filtration option for installation at the main water line.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eAlkalizing Filtration for Whole-Home Water Treatment\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe included alkalizing cartridge uses calcium carbonate media along with mineral and ionizer media to help raise pH and add minerals back into the water.
