Traditional chlorine products contain cyanuric acid (CYA). When too much CYA builds up, it can cause over-stabilization or chlorine lock and cloud your water. The fast-acting, fast-dissolving Cal Hypo formula in HTH® Pool Care Shock Advanced provides chlorination without adding extra CYA for a beautiful sparkle all season. This product is great for all pool types and won't fade your pool liner. How To Use HTH® Shock Advanced Follow the on-pack instructions according to your pool size to add HTH® Shock Advanced directly to swimming pool water or skimmer. Make sure to use a clean, dry scoop. For best results, apply HTH® Shock Advanced as part of your weekly pool care routine to keep free available chlorine levels between 1 and 4 ppm. Multi-functional shock treatment for weekly use Prevents bacteria & algae Use weekly to solve 90% of pool water problems within 24 hours Restores crystal clarity in 24 hours Visibly brilliant sparkle This Cal Hypo based formula sanitizes without adding cyanuric acid (CYA) to prevent over-stabilization or chlorine lock.
