It would be a perfect world if your pool could close itself down for the season, but unfortunately that’s not the case. To be sure your pool is closed down properly for the Canadian winter months, I have put together some tips, that will help you save money and make your pool easier to open in the spring.
BALANCE YOUR POOL WATER
- ADJUST the pH, Alkalinity and Calcium Hardness - having these balanced will protect your pool from corrosion or scale buildup over the winter. Adjustments should be made 5 days prior to completely closing the pool.
- pH should be between 7.6-7.8
- Alkalinity should be between 80-120 ppm
- Calcium Hardness should be between 180 to 220 ppm
- Shock the water with chlorine - this will kill any bacteria that may be living in the pool water. If you normally use a shock treatment that allows people to reuse swimming shortly after, it probably is not strong enough to kill all bacteria in your pool. Since closing, it may require a stronger treatment depending on closing water test. Let chlorine level return to 3ppm-5ppm over the course of a few days before proceeding.
- Algaecide - kills existing algae and prevents more from blooming, so it is important to treat your pool with an algaecide before shutting it down. Make sure chlorine has returned to 3ppm-5ppm before adding algaecide, or the chlorine will render the algaecide ineffective!
* extra-strength algaecide - helps to prevent algae from blooming prior to the cold winter season & protect in the spring
CLEAN THE POOL
- REMOVE everything from the pool that’s NOT water - ladders, baskets, hoses, filters, pumps, heaters, and any decorative pool fittings.
- Rinse all of the pool equipment and lay it out to thoroughly dry!
- Store equipment in the garage, shed, or another dry place through the winter. Use a nylon bag and store together. Makes an easy find in the spring
- Vacuum, brush and skim the pool!
- Clean the Sand - find tips on cleaning & changing the sand HERE in a past blog post
LOWER THE WATER LEVEL
Lower the water level below the skimmer according to the type of pool cover you use.
- Mesh Cover: lower 12 to 18 inches below the skimmer
- Solid or Floating Cover: lower 3 to 6 inches below the skimmer
- Closing Full: use the correct winter plugs (duck plugs) and gizmos (ultra)
DRAIN THE EQUIPMENT
- Pumps, filters, heaters and chlorinators need to be drained of water before closing - if water freezes inside the equipment, it could severely damage it.
- Remove CARTRIDGE filters and clean them thoroughly - store them in a dry place
- Winterizing the lines- use a shop vac to blow air from the skimmer through the equipment and back into the pool.
- Add swimming pool antifreeze to the lines to prevent any remaining water from freezing
- Use expansion plugs to plug the lines at the pool & foam rope for skimmer & jets.
If you’re hesitant about closing your swimming pool yourself, or have questions, please do not hesitate to ask. A simple mistake when winterizing your pool could prove to be costly a few months later.
