How To Close Your Pool Down For Winter In 5 Easy Steps

Unless you are fortunate enough to enjoy 12 months of sunshine per year, you will be familiar with those chilly months all too well. If you have a family pool that sees a lot of action in the summer, how do you deal with it during those bleak seasons? Some of us just forget that the water feature ever existed and then act all surprised when the pool resembles a floating dustbin 5 or 6 months later. There are some very simple but effective tips that can save you some money and a lot of hard work in the meantime. This article is focusing on how to prepare your swimming pool for the winter months – Enjoy!

Sort Out The pH Balance!

Before letting your pool have a well-earned break, it is advisable to balance your levels and these include alkaline and calcium as well as the pH level. Try to ensure that you have done this about 5 days before your winter close down commences. If you are in any doubt as to the correct levels, here they are:

  • Ensure that your pH level is between 7.2 and 7.6
  • Adjust the alkaline level to between 80 and 120 parts ppm.
  • Calcium hardness needs to sit between 180 and 220 ppm

Water Shocking

By shocking the pool water you are killing any living bacteria that is currently residing there. This can be done by using a chlorine or non-chlorine substitute, and try to get a product that contains at least 65% sodium hypochlorite. Don’t just pour the substance into the pool, use a 5 gallon bucket and fill it with pool water, then add the correct amount of granules and pour it into the pool. Ensure that the filtration system is running and choose a product that doesn’t say it is safe enough to swim with straight after administering. This type of shock treatment is probably not strong enough to work properly.


Pick a decent winterizing algaecide and this will stop that hidden algae from blooming in the winter months. Before you add this powerful additive, ensure that your chlorine levels are between 1 and 3 ppm, otherwise the algaecide will not be effective. Try and pick a strong algaecide and not a ‘safe’ derivative.

Clean it!

If your pool is in a decent state before the winter begins, you’ll have a better chance of finding it in a nice condition when you start using it once more. The best way to ensure your pool is correctly cleaned is as follows:

  • Remove all equipment and features, this includes filters, hoses and the pump.
  • Skim the pool and remove any loose debris.
  • Vacuum and brush the pool

Lower the Water Level

Ensure that the level is about 12 inches below the skimmer if you are using a mesh cover. If you are using a floating cover, lower the level about 3-6 inches below the skimmer level.

Look Forward To a Nice Poll in About 4-5 Months!

Enjoy your winter break and get ready to see a nicely rested pool when the weather finally breaks in the spring!
