What Causes Pool Algae?

Before jumping into removal tips, it’s essential to understand what causes algae growth in your pool.

  • Poor Circulation: Stagnant water creates an ideal condition for algae to thrive, especially in corners or shaded areas where circulation is weak.
  • Imbalanced Water Chemistry: Incorrect pH, chlorine, or other chemical levels allow algae to bloom and spread.
  • Lack of Regular Cleaning: If pool equipment or surfaces aren’t maintained regularly, algae spores already in the water can multiply.
  • Warm Temperatures: Algae spores flourish in warm conditions, especially during hot Florida summers.
  • Contaminated Equipment or Swimmers: Algae can be introduced via swimsuits, pool toys, or equipment that hasn’t been cleaned properly.

By addressing the “why,” you can stop algae growth before it begins. But if it’s already taken hold, read on for our best tips.

Identifying Types of Pool Algae

Not all pool algae are created equal. Some types are easier to remove, while others require more intensive treatment. Here are the main culprits seen in pools across Winter Park, FL, and beyond:

1. Green Algae

Green algae are the most common type and often turn your water cloudy and green. While unsightly, it’s relatively easy to remove with chlorine shock and brushing.

2. Yellow or Mustard Algae

This type of algae clings to pool walls in shady areas and is more challenging to remove. It easily brushes off but can quickly return if not treated thoroughly.

3. Black Algae

Black algae form dark spots with deep roots that anchor into pool surfaces, making it the most stubborn of the three. Cleaning black algae requires aggressive scrubbing and algaecides.

Identifying the algae type will guide your approach to clearing your pool.

How to Remove Pool Algae in 6 Simple Steps

If you’ve identified algae in your pool, don’t worry—here are the steps to remove it and restore water clarity.

Step 1: Test and Balance Water Chemistry

Start by testing your pool’s chemical levels using a pool test kit. Pay particular attention to pH and chlorine levels. The recommended ranges are:

  • pH: 7.2 to 7.5
  • Chlorine: 1-3 parts per million (ppm)

Adjust the water chemistry before beginning treatment to ensure effective algae removal.

Tip: Slightly lowering the pH to around 7.2 can make chlorine more effective against algae.

Step 2: Brush the Walls and Floor

Use a stiff pool brush to scrub algae off pool walls, floors, and other surfaces. Brushing breaks up the algae's protective outer layer, making treatments more effective.

  • For Green Algae: Focus on brushing all visible surfaces thoroughly.
  • For Black Algae: Use a stainless steel brush to reach deep root structures.

Don’t skip this step—brushing is critical to freeing algae from its grip.

Step 3: Shock the Pool

Shock treatment is your best ally when it comes to eliminating algae. Add a chlorine-based shock product to your pool following the manufacturer's instructions.

For severe algae outbreaks, double the recommended dose to ensure complete disinfection.

  • Green Algae: Single shock treatment recommended.
  • Yellow Algae: Double shock may be required.
  • Black Algae: Use a triple shock treatment combined with scrubbing for best results.

Allow the pool pump to run for 24 hours to evenly distribute the chemicals.

Step 4: Use an Algaecide

After shocking the pool, apply an algaecide specifically formulated for your algae type. This step helps ensure any lingering spores are destroyed.

Choose an algaecide that is safe for your pool finish and compatible with your current chemical treatment.

Step 5: Clean the Filter

Algae fragments and debris will accumulate in your pool filter during cleanup. To avoid reintroducing spores back into your water, clean or backwash the filter thoroughly.

For cartridge filters, remove and rinse. For sand or DE filters, follow the manufacturer's backwashing instructions.

Pro Tip: If the algae problem is severe, consider replacing your filter media entirely.

Step 6: Monitor and Maintain Water Circulation

Once the algae are removed, proper circulation is essential to keep your pool healthy. Run your pool pump for at least 8-12 hours per day, especially during Florida’s warm months.

Inspect your pool circulation system regularly to ensure no dead spots where algae can grow.

Algae Prevention Tips

The best cure is prevention! Here’s how to keep algae out of your pool long-term:

  • Test Water Weekly: Monitor pool chemistry weekly and after heavy rainstorms to prevent imbalances.
  • Brush and Vacuum Regularly: Keep debris off pool surfaces to block algae's food sources.
  • Use a Pool Cover: When your pool isn’t in use, cover it to block out sunlight that algae thrive on.
  • Invest in Filtration: Upgrade your pool's filtration system if circulation is a recurring issue.
  • Regular Maintenance: Schedule consistent pool service with experts, like Pure & Simple Poolcare in Winter Park, FL, to ensure your pool remains algae-free year-round.
