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.
