How It Works Calcium ions, magnesium ions and bicarbonate ions in untreated water form scale on the inside walls of pipe, exterior of fixtures and on heating surfaces because crystallization is not taking effect efficiently between the ions due to their suspension between water molecules and the need to come together in the proper alignment to form crystals. Therefore they form as scale on the surfaces of the water system. The system is a simple “physical water treatment” known as TAC (Template Assisted Crystallization) Inside the TAC treatment tank are porcelain beads with the atomic level pattern of the crystal etched on their surface allowing for the calcium, magnesium and bicarbonate ions to come together on the template to created millions of microscopic crystals of scale that rapidly form and are released from the bead immediately into the treated water, not forming on the contact surfaces of the water system and are carried downstream in suspension through the water system. The crystal formation on the microscopic crystals (seed crystals) created on the beads and released in the water stream are the lowest energy reaction possible between the ions therefore existing scale will be dissolved back into the water stream by reacting with and forming crystals.
