    Closing Kits

    1. 2 years ago
      If you care about your pool - buy this!
      As my pool has aged, opening it has been more difficult year after year. I live in the Midwest so we get very cold winters and lots of sun in the Spring. More algae appeared year after year and I just accepted it. Would take me 1-2 weeks to get the pool clear. Found this last year and used the kit. Absolutely amazing! When I closed it last year, I followed the instructions in the kit (very easy). I then added another bottle of winter algaecide in early March. When I opened the pool in April, the ... read more water was very clear. I had the pool ready to swim in 2 days.

      Easy to close and easy to open
      We have used In The Swim Pool Chemical Winterizing Kits for several years for our above ground pool, in-conjunction with an air pillow and a good winter cover. The kit is very easy to use, instructions are very clear. Every spring our pool is beautiful and clear, ready to top off, add In The Swim Pool Chemical Opening Kit and it's all ready for the season!

      Excellent product!
      I have been using this closing kit for past five years. Never a stain when I open in Spring unlike previous openings that I had professionally done.

      Quick delivery, but missing one item
      I placed the order, and received the winterizing kit in two days. However, the quote Magic Ball unquote was not in the kit. I had to call back and advise them of this. They did ship out the missing item immediately, and I received it the next day. We will see how the pool looks when I open it in the spring.

      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!!

      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.

      Fine product from a fine company
      Very predictable. Works great on 16 years of pool openings for summer. No residue and easy to use. I've got some of my friends now using In The Swim products. Their next business day service can't be beat!

      InTheSwim Instructions Almost Always Lacking
      Guys, you've GOT to get it together on your opening and closing instructions. The closing instructions shown on the website page above these comments tell us to add Pool Magic first, Phosphate Remover second, Shock third. Your printed instructions with the kit say to add Shock first, WAIT a half-hour, and then add Pool Magic and the Phosphate Remover. Your online directions tell us to lower the pool level BEFORE adding anything. Anyone who does will soon realize that the pump STILL needs to be ... read more running for all of the chemicals, so lowering the water would have been a big mistake. The product is great and I really enjoy purchasing from your company, but I can't understand why you can't be clearer in these situations.

      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 complete kit that works!
      I have purchased this winter closing kit for 3yrs in a row for my 20k gal. gunite pool. Kit comes with directions and the float lasts all winter long. I have opened my pool each spring to find it as I closed it ...clear, no algae. I also use a solid cover with water bag weighs . Will continue to use this kit

      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.

      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.;

      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.

      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)!

      Must Have For Closing Pool
      I used this product when I closed my pool and when I uncovered it in the Spring - the water was still crystal clear. You couldn't tell it had be covered all winter. Wonderful product!

    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
