How to Remove Algae From Pools Quickly and Safely

Keeping a pool clean in Florida isn’t always easy. With Punta Gorda’s humid summers, Port Charlotte’s sudden storms, and North Port’s year-round sunshine, algae can sneak up fast. If left untreated, it turns your crystal-blue pool into a green swamp that’s unsafe for swimming. Luckily, removing algae doesn’t have to be stressful—if you know the right steps.

In this guide, we’ll walk through safe, effective methods to get rid of algae while protecting your pool equipment and your family’s health.

Why Does Pool Algae Grow in Florida?

Florida’s unique climate creates the perfect breeding ground for algae. High humidity, frequent rain, and constant sunshine make it tough for homeowners in Charlotte County and Rotonda to keep algae under control.

Common causes of algae growth include:

• Imbalanced pool water chemistry
• Poor circulation or clogged filters
• Warm, stagnant water
• Debris buildup from storms or landscaping
• Infrequent pool cleaning schedules

💡 Local Insight: After a heavy rain in Punta Gorda, chlorine levels often drop, which allows algae spores to multiply quickly.

Types of Pool Algae You Might See

Not all algae are the same. Understanding the type helps you choose the right treatment.

1. Green Algae – The most common, causing a green tint or slimy walls.
2. Yellow/Mustard Algae – Appears as yellowish patches, often resistant to chlorine.
3. Black Algae – Tough, root-like growth that sticks to walls and requires extra effort.

Step-by-Step Guide to Removing Pool Algae

Step 1: Test and Balance Your Water

Before adding chemicals, check your pool’s pH, alkalinity, and chlorine levels. The ideal range is:

• pH: 7.2–7.6
• Alkalinity: 80–120 ppm
• Chlorine: 1–3 ppm

If the levels are off, adjust them first. Balanced water makes treatment more effective.

Step 2: Brush the Pool Surfaces

Use a stiff-bristle brush to scrub walls, steps, and ladders. This loosens algae so chemicals can penetrate.

• For green algae, a standard pool brush works fine.
• For black algae, use a wire brush for stubborn spots.

Step 3: Shock the Pool

Shocking means adding a high dose of chlorine to kill algae quickly.

• Use 3–5 times the normal dose for green algae.
• For yellow or black algae, increase shock dosage and repeat if necessary.

Make sure your pool pump is running for 24–48 hours to circulate the chlorine fully.

Step 4: Run the Filter Continuously

After shocking, keep the filter running until the water clears. Clean or backwash the filter regularly to remove dead algae.

Step 5: Vacuum to Waste

If there’s a lot of dead algae, vacuum your pool directly to waste instead of through the filter. This prevents clogging and speeds up recovery.

Step 6: Add an Algaecide (Optional)

Once the pool is clear, you can add an algaecide to help prevent regrowth. Look for products labeled as non-copper-based to avoid staining.

Preventing Algae in the Future

Living in Charlotte County means algae will always be a threat, but prevention keeps it manageable.

• ✅ Test pool water at least 2x per week
• ✅ Keep chlorine levels steady
• ✅ Brush walls and steps weekly
• ✅ Clean filters and skimmers regularly
• ✅ Schedule weekly pool cleaning in Charlotte County with a professional for peace of mind
