Description
Restore your pool’s brilliance in under a day with HTH Ultra Shock (Model 52039), a potent calcium hypochlorite granular shock treatment built for weekly pool care. This rapidly dissolving, multi-action formula surges chlorine concentration to obliterate bacteria, algae, stains, and scale buildup while simultaneously minimizing skin and eye discomfort and enhancing filtration performance. Because it introduces zero cyanuric acid, there is no risk of stabilizer accumulation or chlorine lock. A distinctive blue activity indicator confirms the product is working, and water returns to sparkling clarity within 24 hours. Safe for vinyl-lined, concrete, and saltwater pools, HTH Ultra Shock delivers professional-grade sanitization in a convenient 1 lb single-use package.
