The Natural Chemistry 17612COR Yellow Out Algaecide is a concentrated granular algaecide specifically formulated to prevent and treat yellow and mustard algae in swimming pools. Yellow algae can be stubborn, forming a slimy coating on pool surfaces that resists standard chlorine treatment. This product ensures clean, clear, and healthy water by targeting these difficult algae types.

Packaged in a 2-pound bottle, it is ideal for residential pools or spot treatments in larger pools. Its fast-dissolving granules allow easy application and even distribution, providing reliable algae control.
