How to Open Your Pool: A Simple Step-by-Step Guide

Open your pool smoothly with these simple steps. This guide covers essential procedures, start-up chemicals, and maintenance tips for a hassle-free season.

When Should You Open Your Pool?

Before opening your pool, take a few preparatory steps to make the process easier. While the cover is still on, clean your pool filter and remove any debris from the cover. If you used a winter cover, pump off any excess water.

Now is also a great time to inspect your pool equipment. Check your equipment pad for any needed repairs or upgrades. Consider installing shut-off valves between the pool and the pool pump if you don’t already have them. If you use a cartridge filter, adding a waste line just after the pump can make maintenance easier.

Tip: Open your pool before the water temperature reaches 60°F. Algae thrive in warmer temperatures, so opening early reduces the risk of green water.

Steps to Open Your Pool

Remove the Cover:

• If you have a leaf net over your winter cover, remove it first to prevent extra debris from entering the pool.
• Clean off any debris and drain excess water from the cover before removal.
• If you have a safety cover, remove the anchor covers first.
• Enlist help when removing the cover, as it can be heavy.

Clean the Pool:

• Use a leaf rake or skimmer net to remove large debris.
• Vacuum silt or sludge from the bottom using a self-contained pool cleaner.
• Inspect skimmers, returns, hoses, and other components for cracks or wear.
• Remove winterizing plugs from the plumbing.

Refill and Restart the System:

• Fill the pool until the water level reaches the middle of the skimmer opening.
• Open all valves to allow water to enter the plumbing system.
• Open the air release valve on the filter (if applicable) until water flows steadily.
• Close the valve and turn on the pump to purge any remaining air.
• If you have a DE filter, recharge it with DE powder.
• Reinstall ladders and handrails.
• Run the pump for at least 30 minutes before testing the water.

Swimming Pool Start-Up Chemicals

Many pool stores sell pre-packaged start-up chemical kits, but these often contain unnecessary or overpriced products. Instead, use a drop-based test kit to check your water chemistry. Adjust the following levels as needed:

• Chlorine: Most pools will have zero chlorine after winter. Add chlorine immediately to prevent algae growth.
• Total Alkalinity (TA), pH, and Cyanuric Acid (CYA): Test and balance these levels before adding other chemicals.
• Salt Levels: If you have a Salt Water Chlorine Generator (SWG), test the salt level using salt test strips and add salt as needed.

Dealing with Green Water?
If your pool is green, you may need to perform a SLAM (Shock, Level, and Maintain) treatment. This involves adding high doses of chlorine and running the pump 24/7 to eliminate algae.

Final Tips for a Sparkling Pool

• Test and adjust your pool’s chemistry daily for the first few days.
• Run your pump consistently to help distribute chemicals evenly.
• Stay ahead of maintenance to keep your water crystal clear.

Opening your pool doesn’t have to be difficult. With the right steps and a little effort, you’ll be ready for a fun and refreshing swim season!
