A single treatment of PristineBlue at the end of the swim season is normally all it takes to keep a pool clear until spring.

“Winterizing” or “Closing” a pool means adding products at the end of the swim season to keep it clear without maintenance during the cold winter months.

1a. Balance water parameters to within proper ranges below.

  • Total Alkalinity: 50 to 90 ppm
  • pH: 7.2 to 7.6

Step 2: Prep

2a. Shock the pool with 1 pound of PristineExtra2 per 10,000 gallons of water.

2b. Run the filter for 4 hours.

2c. Clean pool and backwash sand filters. Thoroughly clean D.E. or cartridge filters.

2d. Add 2 ounces of PristineClean per 10,000 gallons of water.

Step 3: Close with PristineBlue

3a. Test the PristineBlue level and add PristineBlue using the Maintenance Dosage Chart below.

3b. Follow the pool and equipment manufacturer’s freeze recommendations.
