AquaDoc Spa Metal Control
First-fill metal ion sequestering formula
A chelating metal control formula that binds dissolved iron, copper, and manganese in the water column at refill, preventing oxidation and surface staining when sanitizer is introduced or water temperature rises. The proactive dose at every refill that prevents the rust-coloured iron staining and blue-green copper staining on acrylic shells that reactive treatment cannot fully reverse. Compatible with all hot tub and spa types.
