How do you winterize a chlorine pool?

Note: Winterization procedures will vary depending on your region, your pool type, and your preferences for how to shut down your pool. Consult your dealer and/or builder about the proper way to store and winterize your equipment and the pool.

  1. Select the appropriate Arctic Blue® Winter Kit(s) for your pool volume. Winter Kits winterize up to 12,000 gallons or up to 24,000 gallons.

  2. IMPORTANT: If any problems exist, such as combined chlorine, cloudy water or algae growth, clear these up before performing a winter water analysis and beginning the closing procedures.

  3. When the pool is clear, perform a winter closing analysis. Balancing parameters are slightly different for winter temperatures than for in-season. Balance according to the ALEX Pro recommendations for winter shut-down.

  4. Do all housekeeping chores. Brush and vacuum. Clean the waterline with Off the Wall®. Cleaning the pool surfaces before shutting down the pool will help prevent permanent staining.

  5. Clean out the skimmer baskets and the hair/lint trap. If the system will not be circulated, remove and store them.

  6. Chemically clean the filter using Strip Kwik® and Kleen It®. Strip Kwik® is necessary to remove oil and grease from the filter. Kleen It® should be used if you have any possibility of scale buildup in the filter.

  7. With the pump running, add the Arctic Blue® Shock from the Winter Kit(s) (1 lb. of Arctic Blue® Shock per 6,000 gallons). Wait one hour.

  8. Add the Arctic Blue® Algae Protector from the kit(s) (16 oz. of Arctic Blue® Algae Protector per 12,000 gallons) around the edges.

  9. Circulate 2-4 hours.

  10. Winterize the equipment as the type of season demands. (In much colder climates, equipment may be removed and stored until spring.) Follow your dealer's recommendation for equipment winterization.

  11. Drain the pool partially if recommended by the builder and install the winter cover.

In warmer climates, it may be necessary to add Arctic Blue® Shock and Arctic Blue® Algae Protector once more through the winter.
