Atlantis Closing Kit – Winterizing up to 60,000 L

Closing a pool without treating the water means paying the price in spring. For six months, the water sits still under the cover. Nothing is filtered, nothing circulates, and organic matter, dormant algae, and dissolved metals have all the time they need to do their work. In May, you open the pool to green or stained water, then spend time and money on chemicals to make up for what you didn’t do in October.

The Atlantis closing kit includes everything you need to get through the winter: the dosage is already calculated based on your pool’s volume, so there’s nothing to measure.
