Clorox Pool&Spa 16-oz Pool Shock

Enjoying your beautiful pool just got easier with the convenience and power of Shock XtraBlue®2. Other pool shocks stop at clearing a cloudy pool, but Clorox® Pool&Spa™ Shock XtraBlue®2 goes beyond other shocks to keep your water beautiful and swim-ready all season. The fast-dissolving pool shock formula not only removes the bacteria and contaminants that can cause cloudy water, Shock XtraBlue®2 also helps control algae growth including common green algae, slimy mustard algae, and stubborn black algae reducing chlorine odor and eye irritation. It works this hard for you without bleaching your liner or affecting pH like other brands of pool shock. Use Shock XtraBlue®2 as part of your weekly maintenance for sparkling, crystal clear water all season long. Test and balance water prior to use. Adjust pH to 7.2-7.6. Dosage 1 lb per 12,000 gal.
