      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.

      Best general algacide
      I have used this product from ITS since the mid-1980s. My pool is a gunite (concrete) pool with an epoxy paint finish (no liner). I've had a salt cell system for a few years and my need for chemicals, other than salt, has dropped dramatically, but I still use Algacide 60+ in thee spring when opening the pool and during the summer if I see any algae at all (my robotic cleaner doesn't get in the corners real well) and I use 1 quart for winterizing. Great product. I've tried some others but have ... read more always come back to this one.

      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.

      Winterizing kit
      I purchased this kit last year to winterize my pool. It just made it so much easier to winterize my pool because I don’t have to guess what and how much chemicals to use. When I opened my pool this spring it was beautiful. Thank you in the swim for your wonderful products.

      Great surprise
      We were skeptical about this kit, but opening our pool was so much easier in the spring. In fact, we bought chemicals in preparation of opening the pool after using the winter kit and did not need to use them. Saved time and money!!

      Good Products, Good Price
      I have been using this kit for the past 7 years to close my in ground pool and it works quite well. My pool opening is easier thanks to the winter chemicals included with this kit.

      Winterization Kit for in-ground pool
      The ultimate winterizing kit is the best way to ensure an easy spring start up season. The package arrived in 1 day and the instructions are easy to follow.

      Instructions
      All quality products but the instructions were a little confusing. It said to punch out the 9 holes in the floater but the floater has 9 holes on each side. I punched out all 18 not knowing, hope it does the job this winter.

      "Great products for pool people at a Great Price"!
      I have been using this kit for years. Follow the directions, and when opening the pool in the spring, it looks as clear as it did when I closed it for the winter. Have never had a bad experience with any products that I purchase from In The Swim. Come to think of it, I buy all my pool products from In The Swim. Thank you for the service you provide and that includes customer service. Kudos !!!

      Great product
      I live in the Deep South , so not much concern about freezing, but this kit does a great job of keeping the pool algae and stain free. It’s my third year of using this, and each time I open the pool it’s just as good as when I closed it. I will continue to use this product and highly recommend.

      THE GREATEST!!
      I have had this above-ground pool since 1987 and this is the BEST product ever. I used it the winter of 2007-2008 and the pool was clean when I opened it. I thought it may have been because we had 100+" of snow. I used it again last winter and the pool was also clear this spring. I have not been using any other chemicals when I close the pool for several year because I never found that they work. THIS DOES WORK!!!

      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

      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!!!

      Does what it’s supposed to do.

      Good deal vs other products
      ITS anti-freeze has never failed to protect my pool
    3. 1 decade ago
      Great anti freeze
      This product I have been using now for 4-5 years. Just fill up your underground pipes with this, seal them off and you wont have to worry about freezing, cracking pip[e, etc... at all during the winter.

      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.
    2. 1 decade ago
      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.

      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)!

    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
