  • Unlike chlorine-based winter kits that reduce the effectiveness of algaecide and other pool winterizing chemicals and can stain, bleach or damage pool surfaces, Our chemical kits won’t damage your pool during winter.
  • In The Swim winter kits include a slow-release winter floater filled with a powerful non-chlorine oxidizer.
  • No staining, no bleaching… just clean, sanitary water
  • Pool water temperature should be at 15 degrees C or below before winterizing.
