    Closing Kits

      Ultimate Winterizing Kit from now on
      Although our pool is just 18,000 gallons we decided to give the Ultimate Winterizing Kit a try when we closed it last year. When we took the pool cover off in the spring the water was much clearer than years past and it took us less time to get the pool up & running. As a result we've decided to use the Ultimate Winterizing kit from now on.

      Last year's experience brought me back!
      I ordered these products a year ago for my pool closing. Since they worked so well last year, my pool was just closed with the same products THIS year!!
    1. 7 years ago
      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.

      A "must have" for closing pool
      When we purchased the ball last fall, I was little doubtful as to how well it would actually work. It was smaller than I was expecting and didn't look like much. HOWEVER..........when we opened the pool this spring the water was clear and I was amazed!! I'm getting ready to order our Winter Ball for this year's closing and I just hope In The Swim has this product as long as we have a pool!!!

      Best Open in 12 years!
      After a warm Winter and warmer Spring, expected to find a very murky pool. We judge opens by how many days after opening day it takes to make out the shape of the white drain cover at 8 foot end. Then how long to see the StSteel screws in the drain cover. WOW saw the screws as soon as the cover came off! Best Open ever -looked the same as when I closed it up.... 6 months ago. Found a dead shrew at bottom of stairs, something like this in a normally murky pool- would have taken "days" to digest ... read more with chemicals- let alone see it and scoop out. So I know I saved time and money and will buy a winter ball for the coming closing in the fall from now on!

      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
      This was recommend by our pool installation contractor. We tried the Pool magic and have used it for the last five seasons.

      I'm sold!
      Short version: this stuff works! Longer version: For the past several years I've been opening my 20,000 gallon (w/ mesh safety cover) pool to find it so green and nasty looking (due to the mesh safety cover), that at times I thought draining it might be a better option. That said, I figured I would give this [Pool Magic Plus Phosfree Pool Cleaner] a try, especially since it was still relatively warm when I closed the pool. I did the normal closing procedure, but this time added Pool Magic ... read more too. Then in March, I added a second bottle (as the product recommends). Well, I just pulled the pool cover off and... WOW! This stuff REALLY works! I was expecting to see the usual algae green water that's so dark and 'thick' you can't see the bottom of the pool (or the steps for that matter). However, this year, not only is the water not green but, for the first time EVER, I can actually see the bottom of the pool (even in the deep end)!

      Pool owner
      After closing the pool I punched the 9 holes in the Winterizing Enhancer Floater container (as instructed in the brochure ) and put it in the pool and it sunk to the bottom. I removed it from the pool and upon examining the container further I discovered it had markings on the container indicating different pool water levels. So the number of punches in the container should be less if a pool contains less water. This information should be listed in the brochure to help customers decide how ... read more many holes to punch in. Otherwise, this is a useless addition to the winterizing kit. PLEASE MAKE THIS ADJUSTMENT IN YOUR BROCHURE TO MAKE THIS PROCESS MAKE SENSE.

      Good product overall
      Pretty much all you need to close the pool. It doesn’t have anything for your pump if you have an I ground pool so be sure to buy that as well.

      Winterizing kit
      Received product quickly ~ everything listed was included. This is our first time to close our pool. We are anxious to open our pool next spring and see how well winterizing kit worked!

      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.;

      winter ball issue
      I bought two winterizing kits with the winter pill. the kits are easy to use. one kit included a sheet on how to winterize the pool but the other didn't have this. The pin to puncture the winter ball was never check by a person ...the body is too big to fit into the hole or the shaft is too short to puncture the seal. An ice pick or long nail worked well.

      Good product with proper use
      We have used the deluxe winter kit for our 15x30 foot above ground pool for many years now. What we have learned is to drop in the winter pill in February to extend the protection of the kit into the spring months when it is still to cold at night to be able to uncover and swim, but warm during the days. We also add algicide to the water once the days warm up to keep mosquito larvae at bay until the pump is up and running.

      Effective algae control
      A whole bottle when opening the pool, then about a third to half a bottle weekly. Save one whole bottle for winter closure.

      Works well for me
      I have been using this product for many years. Along with Calcium Hypochlorite, it has kept my pool algae-free. I like this algaecide (amber-colored and viscous) better than the blue stuff, which I think might be a blend of algaecide and clarifier.
    3. 9 years ago
      Works The Best!!!
      I have used Algaecide 60 plus for years and love it! I previously purchased the "name brands" at local stores because they were cheaper. Well, they were not cheaper in the long run! I would use more and more without noticeable clearing of the pool water. When I finally switched to Algaecide 60 I was not very confident that I would see an improvement. I was wrong! It may cost more than the other initially, but it last a long time if used as directed. It helps keep my pool sparkling all season! I ... read more recommend it to all pool owners!

      No Worries
      The fear of water freezing in your pool lines and causing lines to burst or other serious and expensive complications that haunts pool owners all winter is put to ease when using winter antifreeze in your pool lines. The antifreeze is easily poured down your lines to prevent water from freezing within and continues to guard against freezing all winter long. In the spring there is minimal clean up. You can not put a price on the reduction of worries this product relieves customers of when ... read more applying winter antifreeze to your lines.

      Anti- freeze at it's best
      I have been using this anti- freeze for over three years and the product works wonders. It does exactly what it is supposed to do and that is protect lines. Excellent product and would recommend to all that have underground lines and plumbing for their inground pools.

    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.


    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
