Weekly Protection Against Scale Buildup
Sirona™ Defend uses a unique blend of organic polymers to prevent scale, help remove existing scale and stop dissolved solids from precipitating. Used weekly, it keeps water clear and spa surfaces spotless.
It goes beyond ordinary scale control and works with all sanitizers.
Prevents and Removes Scale
Hot water and evaporation concentrate minerals that form crusty scale on shells, jets and heaters. Defend's polymers stop new scale and help remove existing deposits.
Your equipment runs more efficiently.
Reduces Cloudiness
By keeping dissolved solids in solution, Defend helps minimize the cloudiness they cause.
Water stays clear between drains.
Easy Weekly Step
