GLB Strike Out Algaecide 1-Quart — Fast, Stain-Free Algae Control for All Pool Types

GLB Strike Out Algaecide is a triple, chelated copper algaecide designed to control green and mustard algae in pool water. This formula is built to minimize staining when used as directed, delivering economical, concentrated algae control that helps keep your pool inviting through warm days and busy weekends. It works across a range of sanitizing setups, including chlorine, bromine, ozone, and saltwater systems, and there is no mandatory waiting period before you swim after treatment.

In real-world use, pool owners often apply Strike Out during the start of the season or at the first signs of algae. The product’s concentrated formula means less product per treatment, which can be appealing for regular maintenance without frequent applications. The result can be clearer water and fewer visible algae, plus the convenience of compatibility with common pool sanitizers and varied pool types. The emphasis is on practical, observable outcomes rather than guarantees, with guidelines to help you achieve consistent results while enjoying your pool sooner rather than later.
