Pool Closing Kits / Winterizing Kits 

For 10,000, 20,000, & 40,000 Gallon Pools

Protect your pool all winter for an easy spring pool opening!

Our pool closing kits / winterizing kits include the pool chemicals you need to close your pool, help protect your pool all winter, and help provide an easy, stress-free spring pool opening. Select a pool closing kit for a 10,000 gallon, 20,000 gallon, or 40,000 gallon pool.

Don't be fooled by winterizing kits that claim to contain a time-release non-chlorine sanitizer - many of these products contain inert ingredients that quickly dissolve. Our pool closing kits contain powerful Suncoast^® Oxidizing Shock & Swim, a non-chlorine ozidizer, Winter Stain & Scale Control, a sequestrant for stain prevention, and Winter Algarid, a winter algaecide. Plus, each of our winterizing kits include FREE Oxidizing Shock & Swim for an even better value!

Each winterizing kit includes:

• Suncoast Oxidizing Shock & Swim: A full-strength non-chlorine oxidizing pool shock to eliminate organic contaminants. Suncoast Oxidizing Shock & Swim oxidizes your pool water without affecting pH or chlorine levels.

• Suncoast Winter Stain & Scale Control: This sequestrant helps prevent rust, scale and corrosion while the pool is closed. Suncoast Winter Stain & Scale Control protects pool surfaces and pool equipment by preventing scale and mineral deposits that may occur in colder water.

• Suncoast Winter Algarid: This winter algaecide will help prevent algae growth while the pool is closed. Our best winter algaecide, Suncoast Winter Algarid is specially-formulated to work even over the harshest winters.
