Enjoying your beautiful pool just got easier with the power of Clorox® Pool&SpaTM Shock XtraBlue®. While removing bacteria and swimmer contaminants*, Shock XtraBlue® with blue algae fighting crystals helps kill and prevent algae growth - including common green algae, mustard algae, and black algae - that can ruin water quality and clog your filter. Best part? The fast dissolving formula prevents surface bleaching and won't affect your water's pH, allowing you to swim 15 minutes after you treat, when chlorine levels are between 1 to 4 parts-per-million. Use Shock XtraBlue® as part of your weekly maintenance for more Marco and more Polo. Swim On!
