Summer may still be going strong, but pool closing season is right around the corner. As cooler weather approaches, make sure you have the right supplies on hand to protect your pool through fall and winter.
Proper winterization can help prevent algae growth, staining, scale buildup, and water-quality issues while your pool is closed. It can also make opening your pool next spring much easier. At EZ Pool & Spa Supply, we offer convenient pool winterizing kits that take the guesswork out of choosing the right chemicals.
Here are three options to help you get ready for pool closing season.
Safe-T-Zone Winterizing Kit for Mesh Covered Pools – Up to 30,000 Gallons
If you use a mesh safety cover, the Safe-T-Zone Winterizing Kit for Mesh Covered Pools is an excellent option. Designed for pools up to 30,000 gallons, this kit is specifically formulated with the needs of mesh-covered pools in mind.
Because mesh covers allow rain and melting snow to enter the pool during the off-season, maintaining water quality throughout the winter is especially important.
The Safe-T-Zone kit includes a 4-pound tablet floater with borate oxidizers and enzymes, stain and scale control, winterizing algaecide, and Phos-X phosphate remover. Together, these products help control algae, staining, scale, and phosphates while your pool is closed.
OnGuard Pool Winterizing Closing Kit – Up to 30,000 Gallons
For larger swimming pools, the OnGuard Pool Winterizing Closing Kit provides a convenient all-in-one solution for pools up to 30,000 gallons.
This kit includes winter algaecide, stain and scale preventative, and a winterizing cartridge with foam collar. The algaecide helps control unwanted algae growth, while the stain and scale treatment protects pool surfaces from deposits and discoloration during the off-season.
OnGuard Pool Winterizing Closing Kit – Up to 15,000 Gallons
Have a smaller pool? The OnGuard Pool Winterizing Closing Kit offers the same convenient approach in a kit designed for pools up to 15,000 gallons.
It includes winter algaecide, stain and scale preventative, and a winterizing cartridge, giving pool owners the essential chemical treatments needed to help maintain water quality during the off-season.
It's a great choice for smaller pools when you want a straightforward closing kit without buying more chemicals than your pool requires.
Get Ahead of Pool Closing Season
Pool closing season can sneak up quickly, especially in cooler climates. Having your pool closing chemicals and winterizing supplies ready ahead of time means you won't be scrambling when temperatures start falling.
Whether you have a mesh-covered pool or simply need a closing kit matched to your pool's water capacity, EZ Pool & Spa Supply has options to make winterization easier.
