    Pool Chemical Winterizing Kits

    SPECIALLY FORMULATED POOL WINTERIZING KITS WILL NOT STAIN OR BLEACH VINYL OR PLASTER POOLS!
    • Unlike chlorine-based winterizing pool chemical kits that reduce the effectiveness of algaecide and other pool winterizing chemicals and can stain, bleach or damage pool liners, In The Swim's winter chemical kits won’t damage your pool during winter.
    • In The Swim's non-chlorine winterizing kits contain a slow-release winter floater that releases a powerful non-chlorine oxidizer to keep your pool fresh all winter long.
    • Our unique winter pool floater removes carbon dioxide, one of algae's primary food sources.
    • No staining, no bleaching... just clean, sanitary water. Our powerful non-chlorine winter pool shock kills micro-contaminants, algae and pathogens.
    • All winter pool kits are pre-measured for your specific pool size. Ordering a larger winterizing kit than your pool size will help protect from winter cover problems.
    • All winter pool kits include complete winterizing instructions.
    • Not for use in winterizing pools using a biguanide based sanitizing system.
    • Ensure peace of mind this fall with a top quality non-chlorine winterizing kit from In The Swim®.

      If your pool size is not listed above follow the instructions below to determine how many gallons of water your pool holds:

      Average Depth

      It is important to determine the Average Depth because it will be used in one of the equations below to determine the total gallons of your pool.

      Deep End (feet) + Shallow End (feet) ÷ 2 = Average Depth

      Now use one of the easy equations below to find your pool’s gallon capacity.

      Rectangular or Square
      Length (feet) x Width (feet) x Average Depth x 7.5 = Total Gallons

      Circular
      Diameter (feet) x Diameter (feet) x Average Depth x 5.9 = Total Gallons

      Oval
      Long Diameter (in feet) x Short Diameter (in feet) x Average Depth x 5.9 = Total Gallons

      Kidney or Free Form
      Long Diameter (in feet) x Short Diameter (in feet) x Average Depth x 5.9 = Total Gallons
