Keep your pool clear and free of algae during the off-season using the Robelle Swimming Pool Triple-Action Winter Kit for Pools Up to 40,000 gal. The multipurpose algaecide can be used in both summer and winter to contain the growth of algae, while the Winter Stain & Scale Control is a sequestrant that helps minimize rust, scale and corrosion while the pool is closed. The full-strength, non-chlorine oxidizing shock kills organic contaminates without affecting the pH or chlorine levels.
