Automatically controls bacteria, pH, scale & corrosion levels for 12 months...

The simplesilver™ block is self regulating and requires no maintenance for one year.

simplesilver™ slowly and constantly releases silicon, oxides and silver ions into your hot tub as water passes over the simplesilver™ block. These monomers combine to form polymers that purify the water by precipitating contaminants and limit the formation of calcium carbonate (scale), corrosion and other bacteria.
Positively charged silver ions, remain stable in water and are very effective in inhibiting growth of bacteria.
