Protect your hot tub from unsightly stains and scale with Natural Chemistry Spa Metal Free®. This advanced metal control formula is designed to bind dissolved metals such as iron, copper, and manganese, preventing them from causing discoloration, staining, or scale buildup on spa surfaces and equipment. Whether you're filling your spa with well water or municipal water, Spa Metal Free helps keep metals in solution so they can be safely filtered out or remain suspended without creating problems.
Metals naturally found in water can react with sanitizers like chlorine or bromine, leading to stained acrylic surfaces, discolored water, and mineral deposits that can shorten the life of heaters, pumps, and plumbing components. Spa Metal Free helps eliminate these issues before they start, making it an essential treatment for every fresh fill and part of a complete spa maintenance routine.
Compatible with all sanitizer systems, this easy-to-use liquid formula helps maintain crystal-clear water while protecting your spa investment. Regular use helps reduce maintenance, improve water appearance, and keep your hot tub operating at its best.
