    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.

    In The Swim winter pool kits come with complete instructions on how to properly winterize your pool. If you still have questions just call our Toll Free Help Desk at 1-800-288-7946...We're here to help! 

    Chlorine-free Shock 
    Chlorine-based winter kits reduce the effectiveness of algaecide and other chemicals by breaking apart the polymer bonds and can also bleach pool walls or damage vinyl liners. Our chlorine-free shock is a powerful oxidizing agent, but is non-chlorine, and will never harm your pool liner. Chlorine Free winter shock also dissolves faster than chlorine, and maintains greater efficacy at a a wider range of pH level.

    Shocking your pool when closing is important to oxidize any organic matter in the pool water, before covering it for the winter. All of our kits contain a premium form of non-chlorine shock that helps burn off any remaining impurities and won't reduce the effectiveness of other chemicals. Chlorine closing kits can also damage a pool cover that comes into contact with highly chlorinated water, weakening the fabric of most solid winter pool covers. 

    Time-Release Chemical Floater 
    Our exclusive time-release floatation device discharges a non-chlorine oxidizing agent into your pool water for weeks after it's been covered. Not only does this winter pool 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 pool floaters, our non-chlorine sanitizer will never stain your plaster or vinyl, even if it sinks to the bottom (follow our easy directions, and it will float all winter).

    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 minerals – 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 mineral staining, even if you are on well water.

    The final step to preventing algae next spring is to pour in our special winter pool algaecide, and our 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 is the perfect "knock-out" punch against algae. Lasts all winter long, even into a warm spring.

    Winter Sorb (TM)  
    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. 

    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
    For winter pool closing, you may be removing some of the water level (never more than 18" below the coping), but don't discount this amount for mesh covers, which will fill up the pool again over the winter. Purchase a winter kit that is the size larger than your actual pool volume.
