Winterized Pool Care: A DIY Guide

Taking quality care of your pool doesn’t end when the pool closes unfortunately. Maintaining a pool is a year round responsibility. At Leslie's, we've helped hundreds of thousands customers open their pools and one thing we've learned over the years is that few quick and easy maintenance steps during the winter can make your spring pool opening a breeze.

Follow these simple tips to maintain your pool water while your pool is closed:

  1. Remove any standing water that might be on your pool cover. If there is snow present,  we don't recommend attempting to remove it as that can cause damage to your pool cover.
  2. Pull back the corner of your pool cover and check to the how your water is doing.
  3. Check your pool chemistry every two months to ensure a balanced, healthy pool. Or, let us do the work for you! Take your water to a local Leslie's store and get your water tested
  4. While some pool chemicals don’t have an exact expiration, it’s recommended that you discard any and all pool chemicals from the previous season. Why? These chemicals lose their potency and will not do the job as its expected to do. And pouring an excess of chemicals can be bad for your pool.
  5. If possible, circulate your water with a submersible pool pump. Remember that circulating water as much as possible leads to a more sanitary pool and ensures a smooth pool opening season.
  6. Add Fresh 'N Clear for every 10,000 gallons of water you have in your pool.
  7. Using an enzyme-based chemical, like Natural Chemistry’s PHOS Free, will help break down any kind of contamination while also removing the risk of having a waterline ring from appearing. Adding this product will help you during pool opening as you won’t need to scrub your pool tile or finish.
  8. Check the following: water bags and air pillows. Re-fill as needed.
  9. Visually inspect your equipment for any signs of damage, freeze, or other conditions that should compromise opening your pool in the spring.

If Needed, Add Algaecide

During winter, your pool is pretty much dormant which means that the water is not being circulated. Uncirculated water means microorganisms can grow because your sanitizers like chlorine slowly degrade and disappear. If you know that the winter season will be under harsher temperatures, it’s recommended that you add algaecide in order to slow down this bacterial growth. This will allow your pool water to charge up the chemicals and help ensure the water makes it through to spring startup without an algae bloom.

Winterizing your pool is important, but did you know winterizing your backyard is also important? What we mean by winterizing your backyard, we’re specifically talking about patio furniture, large outdoor storage spaces, plants and other outdoor equipment you might own. These items should be securely tied down or moved to avoid damaging your pool cover should there be strong gusts of wind or heavy rain or snow.
