Single-dose shock, and the thing to reach for after heavy rain, a pool party, or the first hint of cloudiness. Shock is a deliberate overdose that burns off the contaminants tabs cannot keep up with — do it at dusk, because midday sun destroys it before it works. See the full Pool Care Supplies guide →
Description
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 provides chlorination without adding extra CYA for a beautiful sparkle all season. This pool shock is great for all pool types and will not fade your pool liner.
