The Ultimate Winter Pool Kit - Large Pool Closing Kits are guaranteed to work or your money back!


Formulated for pools up to 35,000 gallons, the Ultimate Pool Winterizing Kit from In the Swim are designed to save you money with a cleaner opening pool - all of our winter closing kits are chlorine free and safer for the environment.

After a long winter, cheaper pool closing kits will run out of chemicals, leaving your pool water unprotected when the water warms up in the spring. Other kits don't pack the powerful punch of the Ultimate Winter Pool Kit and may leave your pool water unsafe for swimming when it comes time to open again.

The Ultimate winterizing pool chemical kit removes the carbon dioxide in the pool water, and makes it unusable by algae as a food source. Other active ingredients in the Ultimate winter kit remove phosphates and nitrates from your pool. This means spring opening is easier, and you can enjoy swimming sooner. The ultimate pool closing kit is a complete pool winterizing kit that includes everything you need including easy to follow instructions to prepare your pool for the winter.

Use the ultimate winter kit on all pool types, up to 35,000 gallons - for smaller pools you get more protection against damaged pool covers or warm springtime temperatures. If your pool is larger, add another Ultimate Closing Kit, or add one of our small pool winter kits, available at low prices.

Protect your pool this year with the Ultimate Winter Pool Closing Kit. You'll pay a little more up front, but spend less time and money opening in the spring. Especially effective for pools with long off-seasons, or for mesh safety covered pools that open green every year.
