Prevents Scales

Features 5

  • Prevents Stains: SpaGuard's Stain and Scale Control enable spa owners to prevent and remove stains caused by iron, copper and manganese, as well as scaling caused by a high level of calcium.
  • No More Scale: Scale or calcium carbonate build-up can cause damage to your spa surface as well as your spa equipment. SpaGuard Stain & Scale Control does a great job of preventing scale by introducing powerful agents that bond to problem-causing calcium ions in your spa water.
  • Clears Water & Filters: Stain and Scale Control's formula bonds to troublesome metal ions in your spa water and filtering them out, eliminating scale build-up that causes cloudy water and can clog up filters, and other metals that cause unsightly stains.
  • Directions: Simply add this powerful liquid formula to safeguard your spa or hot tub from threats. Apply directly to water, allow pump to circulate water for 30 minutes. Apply weekly as a part of routine spa maintenance.

This is the only product that my husband and I have used in our hot tub. We always use the spa guard brand of everything and have always been very happy for the past 10 years. Our hot tub has always met the requirements for all the chemicals with using this product.
