5 Steps To Remove Algae from Your Pool Quickly

Algae can quickly turn your beautiful, clear pool into a green, murky mess. If you notice slippery walls or cloudy water, it’s time to act fast before the problem worsens. At EZ Pool & Spa Supply, we understand how important it is to restore your pool’s sparkle quickly and effectively. Here’s a straightforward, step-by-step guide to removing algae from your pool fast and keeping it crystal clear all season long.

1. Vacuum the Pool to Waste
Manually vacuum your pool with the filter set to “waste” to remove algae and prevent it from recirculating back into the water.

2. Brush All Pool Surfaces
Scrub the walls, floor, and steps thoroughly with a pool brush to loosen algae and expose it to treatment.

3. Test and Balance Water Chemistry
Check pH, alkalinity, and chlorine levels. Adjust pH to around 7.2 to maximize chlorine effectiveness and create an environment less favorable for algae growth.

4. Shock the Pool
Apply a chlorine shock treatment in the evening to kill algae quickly. Follow product instructions carefully for dosage based on your pool size.

5. Apply Algaecide and Run Filter Continuously
Add an algaecide suited to your algae type to prevent regrowth. Run your pool filter continuously until the water clears, cleaning or backwashing the filter as needed.

Additional Tips:

  • Use phosphate removers if phosphates are present, as these feed algae.
  • Repeat shock and brushing if algae persist.
  • Maintain regular weekly cleaning, water testing, and chemical balancing to prevent future outbreaks.

Following these steps will restore your pool’s clarity and keep algae under control throughout the season.
