The water may freeze to a certain level (depending on the outside temperature). You can prevent the surface from closing over completely by using a Pond Air pump or heater. Our UK test pools have coped with some harsh weather over the winter (without any heaters.) and the liner, surround and the fish all survived well.Another option to help prevent freezing is to add a product such as Pond Guardian Tonic Salt (never use regular table or sea salt). These carefully balanced salts decreases the freezing temperature of water and are also an added benefit to the fish as they prepare for winter.If it has been a while since you built your pool, and we know it will be thanks to its long lasting construction, you can always use our video tutorial to show you the correct way to clean the windows, liner, waterfall or any other accessories you might have purchase, and even move it to a new location should you wish, all of our videos can be seen by following our link below, but please note that you will not be able to purchase our product or accessories, all of our Affinity products and spares are listed on Amazon.Box Contains
