Pool Closing Algaecide

To prevent pool algae during the winter, In The Swim Winter Algaecide plays an important role. Winter Algaecide's powerful and highly concentrated copper-based formula is used to kill small, isolated blooms to control and prevent pool algae growth. Like other algaecides, metallic pool algaecides use metal ions that are positively charged and attach themselves to algae, where they penetrate the outer cell walls, poisoning the enzymes within the algae nucleus.

Usage Directions
