SPA METAL FREE
Spa Choice Metal Free is a sequestering agent that prevents metal staining and corrosion in your spa or hot tub.
Apply Spa Choice Metal Free every time you fill or refill your spa or hot tub to sequester the metals that normally appear in your tap water. Metal Free also prevents scale build-up.
Spa Choice Metal Free keeps iron and other metals from oxidizing, which can cause staining to the spa's finish. Metal Free protects your spa / hot tub finish, as well as the plumbing system and heater.
