The Mineraluxe Cube is the star of the Mineraluxe system. It�s an advanced weekly mineral treatment, featuring a blend of natural minerals fused with advanced cleanse and repel technology. It will leave your hot tub squeaky clean and will dramatically reduce the scaling of heaters, jets, surfaces and equipment. It also dramatically improves the softness of the water, making it more comfortable and less irritating. When Mineraluxe Cubes are used weekly, other common treatment products are no longer needed (stain & scale controls, clarifiers, enzyme cleaners and other water enhancers) saving you time and money.
