      Get the Ultimate Pool Winterizing Kit from In the Swim and prepare your pool for a long winter. Not only do our pool winterizing kits 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 pool chemical 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. If your pool is smaller, you will get more protection against damaged pool covers or especially warm springtime temperatures.

      To figure out your pool size, multiply the pool Length x Width x Average Depth, then multiply by 7.5 (5.9 for round/oval pools). 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 mesh safety covers that open green every year.

      If you love your mesh safety cover, but hate the way it looks when it comes off every spring – try the ultimate winter pool kit – you’ll be astounded at the results!

      Rated 5 out of 5 by from Great winterizing kit We used this kit last year and our water was nearly perfect in the spring, even after loosing our cover halfway through the winter. The only downside is that you need to wait until the water temperature is constantly below 65.

      Rated 5 out of 5 by from Best pool closing kit I've ever found! I have used this product for several years now with great results! It comes with very specific instructions. Have had a clear pool at every spring opening. I made the mistake one year to buy a closing kit from a local pool store and had awful results at opening. Pool took forever to clear up. Learned my lesson and went back to this product. Will never use another brand again.

      Rated 5 out of 5 by from Excellent customer service I placed an online order for the winterizing kit, and after I hit "complete order" I realized I forgot to get a pillow for under the cover. I ordered that, with a note about just ordering the kit and would it be possible to combine the orders so I wouldn't have to pay shipping twice. Two boxes arrived, with an invoice in the pillow box - no shipping fee. Thank you very much!

      Rated 5 out of 5 by from A must use product I have used this kit for the last 5 years for my inground pool and when I open in the spring I have a lot less work in getting it ready for the swimming season. We have had our pool for 14 years and since using the winterizing kit there is a big difference in the water when it is open in the spring. The water is not clear but I can see the bottom in the deep end where before I could not and always had a lot of algae.

      Rated 5 out of 5 by from Works well This is the third season using this winterizing kit has always works Great before !!!!!!!
