Have you walked out to your backyard only to find your once crystal-clear pool has turned an unsightly green? If you’re wondering how to treat a green pool, you’re not alone—this common issue plagues many pool owners, especially in humid, subtropical climates like Miami-Dade and across South Florida.

A green pool is typically caused by algae growth, often resulting from imbalanced water chemistry, insufficient filtration, or neglected maintenance. But don’t worry—M&M Pool & Spa Services has the expertise and reliable solutions to get your pool back to sparkling condition safely and efficiently.

Step-by-Step Guide on How to Treat a Green Pool

Step 1: Remove Debris Immediately

The first step in green pool recovery is to remove all visible debris such as leaves, twigs, and other organic matter. Use a leaf net or skimmer to clear the surface and bottom of the pool. This step is essential to minimize further contamination and to allow pool chemicals to work more effectively.

Step 2: Test and Balance Your Water Chemistry

Before applying any algae treatment, it’s crucial to analyze your water’s chemical levels. Use a reliable test kit to measure pH, chlorine, and alkalinity. For effective shock dosing, your pH level should ideally be between 7.2 and 7.6. At M&M Pool & Spa Services, we assess your water’s chemical profile both on-site and with detailed lab analysis for precise treatment.

Step 3: Shock Dosing – The Core of Algae Treatment

Shock dosing involves adding a concentrated dose of chlorine or other oxidizing agents to eradicate algae spores. For moderate to severe algae infestations, a high chlorine dosage—sometimes 2-3 times the recommended daily amount—may be required. Ensure your pool pump and filter are running continuously during this process to circulate the chemicals effectively.

Step 4: Brush and Vacuum the Pool

After shock dosing, brush all pool surfaces vigorously—including walls, steps, and corners—to dislodge algae biofilm. This makes it easier for chlorine to act. Follow up with a thorough vacuuming to remove dead algae and contaminants from the pool floor.

Step 5: Continuous Filtration and Monitoring

Run your pool filter non-stop for at least 24-48 hours after shocking. Regularly backwash sand or DE filters, or clean cartridge filters, to maintain optimal water flow. Retest and adjust your chemicals as needed. M&M Pool & Spa Services offers ongoing maintenance programs to monitor chemical balancing and ensure a healthy pool environment year-round.

Types of Algae and Their Specific Treatments

Different algae types require tailored treatments:

Green Algae

The most common culprit in green pool water. Responsive to standard chlorine shock treatment.

Yellow (Mustard) Algae

More resistant and usually found in shaded areas. Requires specialized algaecides in addition to shock dosing.

Black Algae

Known for penetrating pool surfaces. Needs aggressive brushing, high chlorine levels, and possibly chemical additions like copper-based algaecides.

Why Chemical Balancing Is Crucial

While shock dosing and algae treatment address immediate concerns, long-term prevention lies in maintaining correct pool chemistry. The ideal ranges include:

  • pH: 7.2–7.6
  • Chlorine: 1–3 ppm
  • Alkalinity: 80–120 ppm
  • Cyanuric Acid (stabilizer): 30–50 ppm

At M&M Pool & Spa Services, we specialize in precise chemical balancing that keeps your pool clean, safe, and algae-free.
