A second-generation blend of organic polymers designed to prevent scale formation, aid in the removal of existing scale and to help prevent precipitation of dissolved solids in spas.

• Prevents calcium's ability to form scale.
• Protects against fouling of filters and equipment failure due to scale buildup.
• Most effective in high temperatures.

Control of calcium can be very challenging, especially is spas. Regular use of SPA DEFENDER will prevent mineral buildup from occurring and causing the spas heater or equipment to fail.
