The media is a catalytically working media using nano-technology developed to first remove already existing scale from pipes and heat exchanger surfaces (de-scaling effect) and further on to protect the system from future formation of scale (scale protection effect). This media is used in a process where atoms are placed in a special structure so that an active surface is created. This technology is so effective that it requires only a few seconds of contact time. It transforms the dissolved calcium carbonate (temporary hardness) so it cannot attach to any surfaces. The chemical bonds are then rinsed away by the water flow. The size of the bonds is so small (in the range of a nanometer) that they can only be seen with a microscope. Therefore the effect is the same as if the water was free of temporary hardness (calcium carbonate). The crystals are heat resistant and do not fall apart under high water temperatures.http://www.watersoftenerscompared.com/compare_water_softeners.html
