How to Close Your Pool for Winter with FROG Pool Tender®

Getting Your Pool Ready for Closing

  1. Balance the water
    Just like at start-up, it’s important to balance your water before closing. Keep Total Alkalinity at 80–120 ppm, pH between 7.2 and 7.8 and Total Hardness 200-400 ppm.
  2. Shock and treat the water
    Shock the water with a nonchlorine shock to rid the water of contaminants and add FROG Pool Tender Algaecide. This is a one-two punch to keep water clean during the winter.
  3. Lower the water level
    Lower the water level to below the mouth of the skimmer to prevent freezing that could damage pipe or the skimmer.
  4. Prep your equipment
    Drain all water from all equipment, including pumps, filters and your FROG Pool Tender Cycler using the knobs at the bottom.
  5. Remove the Chlorine Chamber®
    If the Chlorine Chamber still has product, wrap it in plastic and store it safely. Discard the Mineral Cartridge, as it only lasts one season.
