Clorox® Pool&Spa™ XtraBlue® Algaecide is the ultimate algaecide solution to kill and prevent all types of pool algae - including swampy green algae, slippery mustard algae, and tough, stubborn black algae. This non-foaming, non-staining treatment clears algae in 24 hours and works great in all pool types. Use as a preventative algaecide weekly if your pool is prone to algae or when the temperature increases during the peak of summer.
Always apply chemicals according to label directions. Circulating pool water when applying chemicals helps disperse chemicals throughout the pool for maximum coverage.
