If you have a pool in your home, then you know how hard it is to properly maintain. An improperly cared for pool, especially during the winter months, can lend itself to a lot of unwanted algae.


If the water in your pool is consistently below 60 degrees, then it is time to get a pool winterizing kit! 

The Why?

Your pool contains very expensive materials that keep it functional. For example, River Pool and Spa states, “The average initial cost for an in-ground vinyl liner pool is $35,000–$65,000.”


In the winter months, surface ice expansion can easily tear through your very expensive vinyl liners! This is an easily preventable issue, but if forgotten– can be extremely costly. 


Many new homeowners think that they can simply cover up their pool for the winter months and be all set. Then, as the weather warms up and you get ready for your 1st swim– you might be disappointed by what you find! 


The Gross Green Pool

Lack of water circulation, filtration and sanitation is an algae’s breeding ground dream come true! You do not want algae in your pool for many reasons. For example, a pool with algae can cause these problems: 


  1. Swimming in a pool with algae can create an itchy rash, inflammation, and severe infections! 
  2. Algae can grow into the lining of a pool with the ability to create expensive tears.
  3. Algae is very slippery! Having algae in or around your pool can increase the likelihood of slips and injuries.
  4. $$ costs! Even a small amount of algae can require more chlorine upkeep, which can then add to your maintenance costs pretty quickly. 

Pool Closing Kit & Solutions

  • Doheny states, that the optimal pool chemicals for closing are:
    pH- Between 7.2-7.6.
    Alkalinity- 80-120ppm
    Calcium Hardness- 180-220ppm
    + Pool Cleaning- that is thorough and does not leave behind any algae that can reproduce once covered. 

However, even if you have optimal pool conditions before covering your pool, you can still grow algae. Therefore, you will need a pool winterizing kit to really make sure your expensive equipment stays safe!


A pool winterizing kit should: actively work to reduce carbon dioxide from the pools water, balance its pH levels, remove grime and waterline scrub, along with keeping winter staining at bay!  


With that in mind– let’s explore some of the BEST pool winterizing kits! 

Top Pick for Most Pools
