GLB Granular Dichlor Shock 1LB – Stabilized Chlorine Shock for Pools

Powerful, Stabilized Chlorine Shock for Crystal Clear Pool Water
Keep your pool clean and free of algae with GLB Granular Dichlor Shock 1LB. This fast-dissolving chlorine shock is trusted by pool owners across the country. This product is a dichlor shock (sodium dichloro-s-triazinetrione). It kills bacteria, algae, and organic matter. It also adds cyanuric acid. This helps protect chlorine from the sun’s UV rays for a long time.

Unlike regular shocks that fade fast, this stabilized chlorine pool shock lasts for days. It is great for regular pool care and recovering after rainstorms.
