SpaGuard Stain & Scale Control - 1qt.

SpaGuard Stain & Scale Control (1qt) is a liquid formula designed to prevent and remove stains caused by metals like iron, copper, and manganese, as well as scale buildup from high calcium levels. It helps keep spa water clear, protects surfaces and equipment from damage, and reduces cloudy water. The formula bonds with metal ions to filter them out, preventing scale that can clog filters.
