Water Softener Alternative using ScaleStop Vs. Salt-Based Water Softeners

Salt-based water softeners remove hardness minerals from water, they remove the  calcium and magnesium hardness from the water.  The advantage to salt-based softening is that the Calcium and Magnesium is removed from the water and everything in your home works better, it saves water and it reduces the chemical load in the environment.

ScaleStop is a water softener alternative that is in the form of an ionic ceramic bead.  ScaleStops is so ionically attractive to Calcium and Magnesium that they break free from the hardness molecule and then crystalize on the ScaleStop bead.   ScaleStop neutralizes Calcium and Magnesium minerals instead of removing them. Although these minerals are retained in the water, they are neutralized by converting them to a crystallized form and they are no longer able to adhere to surfaces like pipes or dishes.  The advantage of ScaleStop is that you never need to add salt to the system and you still live with about 70% of the benefits of salt-based softening.

If you're looking for an alternative to salt-based water softeners, the San Diego Pure Water ScaleGuard system has the added advantage of CopperGuard media in each unit.  All ceramic bead water softening media has a weakness when it comes to Copper, Copper can foul the softening media rendering it useless.  ScaleGuard is only offered by San Diego Pure Water.  

Overall, ScaleGuard using Salt-Free Technology is an excellent choice that will exceed your expectations.
