While preparing to close your swimming pool at the end of Summer you may be wondering what chemicals you put in the pool? There’s an easy way to close your pool for the Winter that even makes opening it back up the following Spring easier and faster!

When to Close (and Open) Your Swimming Pool

When should I close my swimming pool for the winter
Before discussing how to make closing your pool easier than you ever thought possible (just wait, it really is so easy), it’s a good idea to understand WHEN to close your pool.

Algae is less active in colder water and more active in warmer water.

For this reason, it is always better to close your pool later in the season when it’s already getting colder out, rather than earlier in warm weather.

Think of early-season closing as an invitation for algae having a late-season party in your pool just to trap it in there all winter. In case you didn’t know, algae is a party animal; the-more-the-merrier type. So that party is just going to get bigger and bigger until it’s time for Spring cleaning.

The earlier you close a pool the more likely the pool is to open up with algae issues, especially if there’s a good bit of warm Autumn weather after your pool is closed.

This is important to be aware of in reverse as well. Open your pool early, not late, to help avoid having a closed pool during an early spring heatwave. A good guideline is: if you can plant your garden, your pool should be open.

Winterizing Chemicals: 3 Easy Steps

Okay, here it is! Are you excited?! Pool chemicals made easy!

  1. Simply use 1lb (or 2 scoops) of E-Z POOL for every 5k gallons of water in your pool. Use our handy dandy Gallon Calculator to help out!
  2. Circulate the pool for 30 minutes before to closing it.
  3. Enjoy your winter and when Spring rolls around, open your pool! For best results, use Revive!, vacuum, and clean your pool.(See before and after Revive! images here).

Additional Winterizing Tips When Closing Your Pool

  • Begin by testing your water and making sure that your pH, Total Alkalinity, and Calcium hardness is all balanced.
  • Add a winterizing chemical kit to your pool. Make it easy!
  • Make sure that you have drained all of your pipes and pool plumbing as water expands when it freezes and can cause your pipes to burst. You can blow the water out from these plumbing lines by using a shop vac or by back washing the pool filter.
  • Lower the water level below the skimmer and plug the return lines.
  • Make sure all pool equipment is removed from the pool and cleaned.
  • Place a winter cover or safety cover over your pool. Here’s more information on winter pool safety!
  • Add air pillows to protect your pool walls as needed.
  • Place a cover pump in the middle of the pool cover to drain any water that might accumulate on the cover.

  • “Just wanted to thank you for a great product. After four weeks of trying several different products and also adding way to much chlorine, we can finally see the bottom of our pool. Added Revive! at 6PM last night, by the time we went to bed, we could notice a difference and when I got up this morning everything had settled to the bottom. Used the vacuum for about an hour this morning and were swimming this afternoon. Will probably have to vacuum once more, but so glad this product was recommended to us.”

  • “Easy, simple, worry free…these all describe how my pool maintenance has been since I started using EZ POOL! I have a big pool and it is not a big job with E-Z POOL, just once a week. Once the pool is open and clear in the spring, I just have Caryl’s experts test my pool sample once a week to make sure the balancing chemicals and pH are good. Algaecides are not needed. Brush, brush, brush, as Caryl recommends and my pool is beautiful all summer! Also, it is gentle to the skin and does not effect your hair color. I highly recommend E-Z POOL!”

  • “I have used the EZ Spa now for four years. It is the best spa treatment I have ever used. It makes the water feel really soft and refreshing. I use it once a week and forget it. My spa stays crystal clear. I love this stuff. Not to mention when you use EZ Spa you don’t have to buy so many other chemicals. I also noticed that EZ Spa is extremely gentle on the skin. I can’t say enough about how good this stuff is. Try it, you’ll love it!”
