In-Ground Pool Closing

Closing your pool properly makes next year’s start-up easy.  To avoid expensive clean-up and repairs follow this easy guide:

  • Keep your filter running for the chemical winterizing treatment.
  • Physically clean the pool. Clean out the skimmer basket and the pump’s hair trap.  If the filter has not been cleaned all season, use Filter Cleaner as directed.  A dirty filter can result in hardened scale deposits that cake over the winter.
  • Adjust the alkalinity to 80-150 p.p.m.
  • Adjust the pH to 7.2-7.6
  • Ensure that your free chlorine reading is between 3-5 p.p.m., or your bromine reading is at least 5 p.p.m.
  • Adjust the calcium hardness to 150-200 p.p.m.
  • Pre-mix one bottle of Stain and Scale in a bucket and pour evenly around the pool. Stain and Scale will guard against scale, metal staining and bathtub ring.  Existing rust stains will also be removed over the winter.  Wait 4 hours before adding the Non-Chlorine Shock.
  • Add 1kg container of Non-Chlorine Shock directly to the pool water to oxidize any dissolved organic matter that physical cleaning and filtration could not remove. The Non-Chlorine Shock works well with both Chlorine and Bromine.
  • Because the fall and spring temperatures are unpredictable, it is recommended that one bottle of Concentrated Algaecide be added to protect the pool from algae. Pre-mix Concentrated Algaecide in a bucket and pour evenly around the pool.
  • Let the pool water circulate 8 hours before shutting down filter.
