Without winterizing your pool, the water could turn green with algae—or worse, bacteria called pink algae can grow. If the chlorine system stops functioning, you'll say adieu to the beautiful blue pool you know and love. Come spring, your pool will be a homely sight and cause a real dent in your wallet.

Properly done, pool closing ensures that when you head back outdoors next summer, you will not have to complete a battery of maintenance tasks before splashing in for your first dip. Winterizing a pool also performs the important role of protecting your equipment from damage caused by freezing.

Shock and Chlorinate Your Pool We recommend shocking a few days before you close the pool. Even if that's not possible, at least treat the water with 1–2 pounds of Fresh 'N Clear non-chlorine shock per 10,000 gallons of water during the closing process.

Closing your pool means that your pool is not currently being used, but could be used again soon. When you close your pool you're most likely not that concerned about freezing temperatures or about water staying behind in your lines or vessels (for example: pump, filter, heater, chlorinator, etc.).

Liner Damage Harsh weather conditions throughout the winter can potentially create new cracks in the liner or expand them further as ice begins to form. Not only is this an expensive fix, it can hinder you from opening your pool in a timely manner when summer comes back around.

Yes! You don't have to close the pool, and you can keep it open year 'round, with or without a pool heater. Or for those in very cold climates, you could also consider a very late closing and early opening, winterizing and closing the pool for just 3 or 4 months, instead of the normal 6 or 7 months.

You will want to close your pool properly over the winter to prevent freezes from damaging expensive pool equipment. Surface freezes can also tear through vinyl liners as a result of ice expansion. A second reason to winterize your pool is because most people completely stop maintenance over the winter.
