      It Works
      I live in the south and have an above ground pool that I do not close for winter. I only have a few trees around and after the leaves have all fallen I clean the pool. We have had a few weeks of 28 degree temps and I always poyr in a bottle of pool anti-freeze to keep the filter and pump from freezing. This stuff works great! When I open the pool (Salt water) I do a shock, and then replace some of the salt that has washed out. Jump in and enjoy.

      It does the job
      I use a couple of gallons when closing in skimmer lines. It's a little pricey, but does the job.

      Winter Algaecide
      I have been using the In the swim winter algaecide for about 12 years.... Works great... I put one quart in at closing and I add a quart about ten day before I open the pool in the spring.....

      Winterizing Wonders
      Third year now that I have used the In The Swim winterizing package for my in-ground pool. Works like a charm and saves the cost of hiring someone to do it for me. This spring, the water needed less attention than prior seasons due to addition of floating clorinator included in the package. Thanks for making opening easier but my former pool guy misses the business. Maybe he'll pay you not to sell your products ??

      Good product
      I have been buying closing kits from In The Swim for several years. The order is delivered promptly. The kit is easy to use and the instructions are easy to follow. The water is always clear when opening in the spring. I will continue to use these closing kits as long as I have a pool.

      They Work Great!
      I had bought some of these plugs when we first set up our 18' above ground pool and they worked great. Now, 8 years later they finally got weather cracked and needed replacement. You can't beat the price considering they kept water from leaking out during the winter for many years. The only change is that the wing nut is now plastic verse metal from 8 years ago. The new plastic wing nut worked great and should last as long as you keep it out of the sun during the summer.

      Wonderful service!

      Excellent product
      I have used Pool Magic for several years now and it has proven to be an extremely effective treatment to jump start my pool opening. I also use it to close up the pool in the fall. Well worth using.

      Great product
      I used this product as part of the deluxe winter closing kit. I will buy an extra bottle next year to keep on hand to prevent any algae, as I always seem to have a problem in the late summer.

      The name says it all! MAGIC!
      We use this product when closing and opening our pool. Before we started using this product we always had a water scum line when we opened the pool. The enzymes in this product break down organics, which prevent scum-line formation. No more scrubby mitt clean-up! This product makes spring clean easy and enjoyable! Highly recommend this product.

      Ultimate Winterizing Kit
      This is the second Winterizing Kit I've purchased from In The Swim. I bought the first one last year for pool closing, and followed the directions. When I opened the pool this spring, this was the first time ever that I found the pool water as crystal clear and beautiful as it was when I installed my winter cover. This kit WORKS, and I'll be buying one every year when I close the pool.

      Straight Forward
      Works as advertised and I have been using these for years. I find the sponge particularly worthless, but whatever, it comes with the kit.

      Good Stuff
      We peeked under the cover in early April this year and the water was crystal clear. We did not open the pool as it was still quite cold. Water temperature was about 50 degrees. One month later in mid May when we did open the pool it was very GREEN. It took a week to clear it up running the pump 24/7. I will use the product again but follow the age old suggestion, CLOSE LATE, OPEN EARLY. The chemicals do have a life span and will not prevent algae from growing indefinitely.

      Great And Easy
      This package is a great package for closing your pool. I have gotten this package for the last 5 years and it works well. Every year when I take my cover off my pool the water is clear as can be. I have used it with an unvented (will not let water into pool) cover and a vented cover and it works well with both. Now with the vented cover you will have the dirt in your pool from the rain runoff that is to be expected however, there was no algae in the water. You can't go wrong with this kit, don't ... read more think about the price think about all the work you will have to do once you open your pool and you didn't treat it for the winter. Just saying.;

      WINTERIZING WAS A BREEZE !
      I was extremely pleased with my winterizing kit. I had everything I needed in the amounts required for my size pool and the instructions were clear, precise, and easy to follow. Closing up my pool was a breeze and I will be back in the spring before I reopen my pool for the season. In addition, once I placed my order - I was kept apprised of it's progress and had my kit in my hands within 48 hours. Very professional company with competitive prices. Gets my vote hands down.

      Best I've ever used
      I have used 4 different techniques/kits since getting a pool. Every other year my pool was green or black when I opened it. Last fall I bought this kit, and this spring when I removed the cover, beautiful, clear water. I've finally found the winner.

      Amazed
      After 14 years of opening a pool to a swamp, the only change was adding this in the closing of the pool 2010. Opening May of 2011 was amazing clear. Even after having 2 90 degree days(which would normally cook up some algea) before we took off the mesh cover, it was the cleariest it has ever been.

      Best yet
      I have had my pool for 18 yrs. No matter what I used in the pool for winter, I would open it in spring to cloudy, green water. Last fall was the first I tried this. I was somewhat reluctant on how a little ball will allow the pool to be so clear when I open it. But it was clear as can be.I can see every little speck of debris that was left in there when I closed it, not to mention the liner pattern so easily seen. I have suggested to all my pool friends to try this

      Works Great!
      I bought this last year around this time and just threw it in and covered my pool. When I opened my pool again at the end of April my pool was a clear and clean looking as it was when I covered it. I didn't use any other closing chemicals, just closed off and drained my pump and let the ball do it's work.

    In The Swim Knowledge Pool: Closing Kits

    In The Swim's Dr. Pool

    Close Your Pool With The Right Winter Pool Chemicals

    During the long off season in the snowbelt – for those that winterize their swimming pool – the water is not being circulated, filtered or sanitized - making your pool the perfect breeding ground for algae. Our winter pool closing kits have been specifically designed and formulated to provide you with the exact combination of powerful winterizing chemicals to help ensure a swift opening next spring, without additional chemicals needed to restore water clarity. All of our In The Swim Pool Winter Kits Include:


    Chlorine-Free Shock

    Our Chlorine-Free Shock is a powerful oxidizing agent, but is non-chlorine, and will never harm your pool surfaces or your pool cover. Chlorine-Free winter shock also dissolves faster than chlorine, and maintains greater efficacy at a wider range of pH level. All of our Winter Pool Kits contain our premium non-chlorine shock oxidizer to burn off any remaining impurities, while not reducing the effectiveness of other chemicals.

    Time-Release Winter Floater

    Our exclusive time-release Winter Floater discharges a non-chlorine oxidizing agent into your pool water for months after it's been covered. Not only does this winter chemical floater sanitize your pool water, but also works to remove carbon dioxide from the water - eliminating one of algae's primary food sources. Unlike chlorine tablet pool floaters, our non-chlorine Winter Floater will never stain your plaster or vinyl. 

    Winter Stain Away

    Specifically formulated for closing your pool, Winter Stain Away helps eliminate stain-causing metals and minerals that can leave your pool with costly liner stains or hard-to-clean waterline build-up. Winter Stain Away sequesters metals – keeping them tied up in solution, to prevent them from precipitating out during winter. Works wonders on mesh safety covered pools, and keeps working all year round to help prevent metal and mineral stains.

    Winterizer

    The final step to preventing algae next spring is to pour in our special winter pool algaecide. Dr. Pool's own proprietary polymer blend combines in perfect harmony with the other items in your pool winterizing kit. When used in conjunction with our other pool closing chemicals our Winterizer Algaecide is the perfect "knock-out" punch against algae. Lasts all winter long, even into a warm spring.

    Winter Sorb 

    Made exclusively for our Winterizing Kits, the Winter Sorb™ can absorb up to 40 times its weight in residual suntan lotions and body oils to prevent grease, grime and waterline scum. Oils are not good for keeping a clear pool that is winterized. They provide a low grade food source for algae, and can clog up the waterways, easily combining with free chlorine to create chloramines, which get in the way of free chlorine trying to do its job.


    Buy the Winter Kit that best fits your pool size. Don't order a kit that's too small, it's better to have some extra chemical in the pool to help guard against cover tears, heavy debris or warm springtime temperatures. And if you close early, or open late in the season, to buy the next larger size winter kit. 

    To help select the best Winter Closing Kit, use these formulas to closely calculate the number of gallons in your pool.
     - Round Pools: Diameter x Diameter x Average Depth x 5.9 = Total Gallons
     - Oval Pools: Long Diameter x Short Diameter x Average Depth x 5.9 = Total Gallons
     - Rectangular Pools: Length x Width x Average Depth x 7.5 = Total Gallons
