HTH Hth 22017r Pool Care Chlorine Granules Ultra, 5 Lbs.

HTH Pool Care Chlorine Granules Ultra is a cal hypo–based chlorinating granule designed to sanitize and maintain swimming pool water. This fast-acting formula kills bacteria and algae while clarifying and softening pool water, delivering visibly sparkling results within 24 hours. Unlike traditional chlorine products that contain cyanuric acid (CYA), this formula provides effective chlorination without adding extra stabilizer, helping prevent chlorine lock and overstabilization that can cloud water and promote algae growth.

This all-in-one pool treatment works with all pool types, including vinyl-lined pools and salt water systems. Its multifunctional action sanitizes, shocks, controls algae, clarifies water, softens minerals, prevents stain and scale buildup, and aids filtration—eliminating the need to purchase multiple products. Simply apply the granules evenly over the deepest part of the pool while the filter pump runs during the evening, following the on-pack dosage instructions for your pool size.
