Once summer passes and the cold months start to set in, it becomes necessary to start preparing your pool for winter. Otherwise, the cold temperatures will damage your pool and equipment, resulting in costly repairs.

      Before winter sets in, you have to clean up, adjust your swimming pool’s pH level, and make other preparations to avoid damage. Learn how to winterize your pool and protect it during the cold months.


      Skim the surface of your pool to remove any leaves, insects, and debris. To clean the bottom, use a pool vacuum. Finally, thoroughly brush the floor and sides.

      It will likely seem like a hassle, especially since you’ll be closing your pool for winter. However, it saves you a lot more time and money later on. Cleaning your pool helps prevent algae and mold growth while it’s closed, and it makes it easier to balance your pool’s water chemistry.

      Test and Adjust the Water Chemistry

      Balanced water is much less likely to damage your pool under freezing temperatures. You need to adjust the water’s pH level and chlorine level as well as add algaecide and shock mixture.

      You can use either pH test strips or a water testing kit to measure pH levels. You should aim for a pH level between 7.4 and 7.8.

      Liquid acids are commonly used to adjust water pH, but you can also adjust your pool’s pH level with a pH control system that uses CO2 instead. It’s also safer and non-toxic.

      Various chemicals are used to raise or lower the other chemical properties of pool water. Adjust your pool’s chlorine level to be between 1 ppm (parts per million) and 3 ppm, alkalinity to be between 100 ppm and 150 ppm, and calcium hardness to be between 175 ppm and 225 ppm,

      Finally, you can prevent algae growth using algaecide and shock mixture.

      There’s a misconception that phosphate remover prevents algae growth since phosphate is a food source for algae. However, the right chlorine level and use of algaecide is much more effective in preventing it.

      Protect Your Skimmer

      Your pool skimmer collects floating debris. However, it won’t be doing much after you cover your pool. And water can crack it if it accumulates, freezes, and expands in the skimmer. So remove the skimmer basket and store it somewhere safe.

      Afterwards, you have two options to protect the skimmer. The simplest is to use a skimmer cover. However, if you opt not to, you can lower the water level to half a foot to a foot below the skimmer. Just be sure to check up on it when it rains and make sure water drains from it.

      Drain and Store Equipment

      Like with the skimmer, water in pool plumbing lines and valves can freeze and expand, causing damage. Disconnect the lines, drain them, and dry them. Drying them is particularly important as mold will otherwise grow in them. Next, remove and clean the filters, then store them somewhere safe and dry.

      Cover the Pool

      Finally, it’s time to cover your pool.

      Place a pool pillow in the middle of the pool and secure it with ropes tied to the sides of the pool. Afterwards, cover the pool, and the pillow, with a pool cover.

      And you’re done!
