What to do with the pool in winter? Check out!

Temperatures have dropped and swimming in the pool is becoming increasingly rare. At this point, the question arises: what to do with the pool in winter?

After all, in the coldest season of the year, few are the ones who risk jumping in the water and, therefore, this beloved space in the house is practically unused.

The fact is that the pool, even when stopped, needs treatment. This is because water that is not treated becomes dirty, it is an easy target for the emergence of microorganisms harmful to health and, in addition, it can compromise the structure of the pool in the long term.

Now, you may be asking yourself: so, does it mean that even in winter it is necessary to spend time and resources on pool care? Well, the answer is that it depends. There is an advantageous alternative that can make this scenario more positive.

What to do with the pool in winter?

Before talking about what to do with the pool in winter, let’s talk about what not to do, which is to leave this structure abandoned. Like, when you don’t do any kind of treatment in the water, it gets dirty, greenish and that brings several harm.

In addition, when you want to resume using the pool, the financial and time expense will be much greater than if you had taken care of the pool during the colder days.

From that point on, you have two options on what to do with the pool in winter: continue its treatment normally, which, of course, means spending more time and money on all the necessary physical and chemical processes, or, on the other hand, hibernate the pool. Have you ever heard of this term?

When we talk about hibernating the pool, we are remembering that concept of hibernation of bears, who spend time sleeping during the winter. In practice, this is basically what hibernation of the pool consists of: leaving it idle, without any use.

For this, however, it is necessary to ensure that the chemical and physical treatment of the water is up to date, in addition to turning off all the equipment that makes it work normally.

How to hibernate the pool in winter: step by step

  • The first step to hibernate the pool in winter is to keep it clean, that is, without dirt accumulated on the bottom or edges. To do this, use a sieve to remove leaves and other things that may be in the water, apply a cleaner around the edges and walls to clean the edges of the pool and, finally, vacuum the bottom to remove all the dirt.
  • With clean water, the next step is to ensure it is in good chemical condition for hibernation. The first thing to do is to evaluate the pH, chlorine and alkalinity to ensure they are at optimal levels, which should be done periodically.
  • Then apply 15 grams of granulated chlorine per cubic meter — a dose equivalent to an emergency treatment — to ensure water purity.
  • Once this is done, the next step is to apply the algaecide, which will keep your pool free of algae and, consequently, of green water. Like chlorine, it must also be applied in large amounts.


However, just be careful not to apply both products at the same time — it is essential to respect an interval of at least 12 hours between applications.

  • After keeping the water in ideal conditions for hibernation, you need to adjust the water level in the pool. Ideally, the water line should be 50 centimeters below the skimmer, as the low winter temperatures cause the water to expand, which is capable of damaging the plastic parts of the skimmer, as well as the tiles next to it. .
  • Another important step is to empty all the pipes with the help of a water or air pump. This is critical because cold weather is dangerous for plumbing and changing water temperatures can break the plumbing.
  • After this process, the next procedure is to turn off the motor pump and all other equipment in the pool, such as fountains and waterfalls.
  • Finally, the last step to hibernate your pool is to find a cover that stays firmly on top of it, ensuring its cleanliness and safety throughout the season.

It is worth mentioning that hibernation is a practical solution not only for winter, but also for when the family is going to travel or stay a long time without using the pool. The step by step is always the same.
