With temperatures rising, it’s time to welcome the long-awaited pool opening season! 

But before you dive in, we have to first complete the necessary tasks for a successful pool opening. Just a few proactive steps could help you save time, money and trouble later on. Starting this process early will help your pool stay clear, healthy, and ready for swimming or relaxing all summer long. 

Let’s take a closer look at how to open your swimming pool.

Your Swimming Pool Opening Checklist

Follow this easy step-by-step pool opening plan to ensure that you’re covering the basics and getting the most out of this pool season.

1. Remove, Clean and Store Your Pool Cover

First, remove your pool cover, clean it and store it away securely. Over the winter months, pool covers can accumulate a lot of dirt and grime. So, make sure your pool cover is clean and properly stored away for when it’s needed again at the end of the summer.

2. Fill Your Pool Up 

Fill your pool’s water surface level to midway up the skimmer openings and tile line. Throughout the week, add pool water as necessary to maintain the correct water level. If needed, be sure you inspect your auto-fill and make sure it is working properly.

3. Clean Out Debris

Debris can sneak into your pool during the off-season. Remove any leaves and other debris that might have gotten into the water when your pool was not in use.

4. Inspect and Clean Your Pool Filter 

You may have performed this task at the end of the last pool season. If not, now is the time to make sure you start the season with a clean filter.  

To make sure your pool filter is still doing its job, here are some important items to address:

  • Check the media cartridges or grids for cracks or holes 
  • If you have a sand filter, change the sand if needed – recommended every 5 years
  • Add new D.E. (after backwashing and before filter startup)  
  • Inspect all O-rings to ensure they properly seal 
  • Inspect the filter gauge to make sure it is still working

5. Reinstall Plugs

Next, it is time to replace all of your winterizing plugs. Reinstall your drain plugs for the pump, heater and filter. Use Teflon tape or another thread sealant to prevent pump air leaks or filter drips.

6. Prime Your Pool Pump and Filter

To get your pool pump and filter ready take the following steps:

  • To eliminate any air in the plumbing lines, make sure to add water to the suction lines with a garden hose.
  • Open the filter gauge pressure relief. Then, mark or document your starting PSI. 
  • Inspect your controller for the correct time, hours of operation and programs for variable speed or variable flow pumps.
  • After the filtration system is operational, inspect all components in the equipment area for leaks
  • Open all suction and return lines, utilize the multi-port valve and clean out any debris in the line by discarding to the waste position. Prior to operating the pool, remember to return the multi-port valve to the filter position.

7. Test and Balance the Pool Water

You’ll want to have a test kit handy to make sure your pool water chemistry is balanced appropriately. Maintaining the proper balance is crucial to keeping your pool water healthy. There are various types of pool test kits you can choose from, such as test strips, liquid reagent kits and digital testers.

8. Shock Your Pool Water

Use a chlorine or non-chlorine shock (MPS) to thoroughly disinfect your pool water. If your pool has algae, use chlorine to eradicate it. Prior to shocking, be sure to brush the algae from the pool walls.

9. Get Your Pool Cleaning Equipment Ready

Check and inspect your pool cleaning equipment. Your pool tool list can include the following: 

  • Telescopic pole
  • Skimmer net 
  • Vacuum head and hose 
  • Leaf vacuum (if needed)
  • Nylon and wire brush
  • Vacuum plate

10. Have Your Pool Chemicals Ready

Make sure you have the correct chemicals available for balancing the water and keeping your pool disinfected, balanced and algae-free. Some chemicals you might consider are:

  • Cal-Hypo or sodium chloride shock
  • Muriatic acid
  • Sodium bisulfate (dry acid)
  • Sodium bicarbonate
  • Soda ash
  • Calcium chloride
  • Algaecide

11. Get Your Clear Comfort Pool System Ready

If you are using a Clear Comfort AOP pool system for additional protection from chlorine-resistant bacteria, pathogens and viruses, please check the blue air tubing and gray one-way air check valve connections. Clear Comfort’s AOP pool system is designed to be powered on when the pump is operational and powered off when the pump is down. 

When your Clear Comfort AOP system is operating, make sure your system’s green LED indicator light is illuminated to ensure the system is working properly. If your system’s light is illuminated yellow or red, it is time to exchange your cartridge. To order a new cartridge, please visit:

12. Set Your Air Flow

Finally, use the flow meter provided with your install kit to inspect the airflow to your Clear Comfort AOP pool system and adjust it 5 to 7 LPM.

Once you’ve completed the steps above, your pool is ready to re-open! Don’t waste any time in the future, and give yourself a head start in prepping your pool for summer.

Enjoy your swimming pool season!
