HTH Pool Care Shock Advanced is a multi-functional pool shock treatment formulated with calcium hypochlorite to provide a powerful weekly boost to chlorine levels. This 4-in-1 formula effectively kills and prevents bacteria and algae growth while reducing chlorine odor and irritation for a more pleasant swimming experience. Unlike traditional chlorine products that add cyanuric acid (CYA) and risk overstabilization or chlorine lock, this fast-acting shock treatment sanitizes without adding CYA, ensuring pure chlorination that keeps your pool water crystal clear. The granules dissolve quickly and are safe for all pool types including vinyl-lined pools, Gunite pools, and saltwater systems without fading liners. Each 1 lb bag treats up to 13,500 gallons of water, restoring clarity in just 24 hours. For optimal results, maintain pH levels between 7.2 and 7.8 and apply shock treatment weekly while your pump is running. This product solves the majority of common pool water problems efficiently, making it an essential part of your regular pool care routine.
