Next-ScaleStop is the embodiment of a new technology, Template Assisted Crystallization (TAC). Near the surface of small specially treated polymer spheres, newly formed micro-crystals of dissolved CaCO3 become preferential Templates or Sites for additional hardness ions as they precipitate. The crystals are relatively insoluble, effectively isolating the CaCO3 from the water chemistry and anything the water contacts such as pipes or fixtures.
