HTH Pool Care Granule Shock Treatment 4.9 lb leak-resistant Advanced pure synthetic formula deliversAbout This Item HTH Shock is the original swimming pool shock designed to boost chlorine levels and kill bacteria and algae for a clean clear pool. Traditional chlorine products contain cyanuric acid CYA. When too much CYA builds up it can cause overstabilization or chlorine lock and cloud your water. The fast acting fast dissolving Cal Hypo based formula in HTH Shock provides chlorination without adding extra CYA for a beautiful sparkle all season.
