Clearwater Enviro Tech offers ScaleBlaster, an innovative and environmentally friendly product that eliminates formation of limescale deposits in household pipes, water heaters, fixtures and showerheads. The integrated circuitry system produces a unique and complex modulating frequency waveform that hits the resonant frequency of the calcium molecules, causing them to lose their adhesive properties. Existing scale is removed and never forms again without the need of chemicals, salt or maintenance. http://www.ScaleBlaster.com, info@scaleblaster.com, (800) 756-7946
