Enjoying your beautiful pool just got easier with the convenience and power of Shock XtraBlue. While removing bacteria and swimmer contaminants, Shock XtraBlue also helps control algae growth – including common green algae, slimy mustard algae, and stubbon black algae – that can ruin water quality and clog your filter. Best part? It works this hard for you without bleaching your liner or affecting pH. Use Shock XtraBlue as part of your weekly maintenance for more Marco and more Polo. Swim On!
Destroy Contaminants Fast
Shock your pool weekly and after pool parties and severe weather to remove contaminants, destroy odors, and keep water clear. No premixing required & dissolves fast! Shock day or night!
Save time when shocking, as our convenient, easy-to-open, easy-to-pour, resealable, recyclable 1 pound bottle of shock will treats 10,000 gallons of water. Always apply according to label directions. For best results, add to the deepest end of the pool with the filter running. Circulating pool water when applying chemicals helps disperse chemicals throughout the pool for maximum coverage.
