Understanding and Combating the Green Invader
If you’ve ever glanced into your backyard oasis only to find it tinged green, you’re not alone. Persistent algae in swimming pools is a common issue that frustrates many pool owners. Not only does it make your pool look uninviting, but it can also be a breeding ground for harmful bacteria and viruses. In this comprehensive guide, we’ll delve into what causes algae, how to eliminate it, and, most importantly, how to prevent it from coming back.
Understanding Algae in Swimming Pools
Algae are simple aquatic plants that thrive in water, especially when conditions are favorable. There are several types of algae commonly found in swimming pools:
-
- Green: The most common type, giving the water a green, murky appearance.
-
- Yellow (Mustard): Looks like pollen or sand and clings to walls and other surfaces.
-
- Black: Appears as dark spots and is the most challenging to remove due to its strong roots.
Understanding the type of algae invading your pool is the first step toward effective treatment.
Causes of Algae Growth
Spores are microscopic and can enter your pool through wind, rain, or contaminated swimsuits and equipment. Here are the primary factors that contribute to algae growth:
1. Poor Water Circulation
Stagnant water is an ideal breeding ground for contaminants. Areas with poor circulation, like corners and steps, are more susceptible.
2. Imbalanced Water Chemistry
Low sanitizer levels (like chlorine) allow algae to thrive. pH and alkalinity levels also play a crucial role in water balance.
3. Insufficient Filtration
A dirty or inefficient filter can’t remove spores effectively, leading to accumulation.
4. Environmental Factors
Debris like leaves and dirt provide nutrients for. Warm temperatures and sunlight further promote growth.
How to Combat Persistent Algae
Eliminating algae requires a systematic approach. Here’s how you can remove algae from your pool effectively:
1. Test and Balance Your Water
Use a reliable testing kit to check chlorine, pH, cya, hardness and alkalinity levels. Adjust them to the recommended targets.
-
- Chlorine: 5 ppm
-
- pH: 7.6
-
- Alkalinity: 90 ppm
- CYA: 40-80 (depending on salt or traditional)
- Calcium Hardness: 300

2. Brush the Pool Surfaces
Algae clings to walls and floors and other surfaces, including toys, ladders, and tools. Use a pool brush to scrub all surfaces, paying extra attention to hidden areas.
3. Clean the Filter
Backwash or clean your filter to ensure it’s functioning optimally. A clean filter helps remove dead debris after treatment.
4. Shock the Pool
“Shocking” involves adding a high dose of chlorine to kill contaminants:
-
- Use a calcium hypochlorite shock for green.
-
- For stubborn algae, consider a sodium bromide treatment or a combination of CalHypo and Algatec.
Always follow the manufacturer’s instructions for dosage.
5. Add an Algaecide
After shocking, use a quality algaecide to kill any remaining spores. This provides a secondary layer of protection. Algatec is a great option if you already have algae in your pool, but we recommend using a PoolRX year-round as a preventative measure.

6. Run the Pump Continuously
Keep your pump running 24 hours a day until the contaminants are gone. This ensures proper circulation and filtration.
7. Vacuum the Pool
After treatment, vacuum the dead debris out of the pool. Use the “waste” setting if available to avoid clogging your filter.
Preventing Algae in the Future
Prevention is always better than cure. Here’s how to keep these pesky problems from returning:
Regular Maintenance
-
- Weekly Testing: Regularly test and adjust chlorine and pH levels.
-
- Brushing and Vacuuming: Keep surfaces clean to prevent spores from clinging.
-
- Skimming Debris: Remove leaves and other debris promptly.

Optimized Circulation
-
- Run the Pump Daily: Aim for at least 8-12 hours of circulation each day.
-
- Inspect Jets and Filters: Ensure they’re clean and directed appropriately.
Use Algaecide Preventatively
-
- Add a weekly dose of Algatec during the swimming season.
Maintain Proper Sanitizer Levels
-
- Keep chlorine levels within the recommended range. Yes, this means you too, salt pool people!
-
- Use a chlorine stabilizer, knows as Cyanuric Acid to protect chlorine from sunlight degradation.
When to Call the Professionals
These issues can be very stubborn. If you’ve tried the above steps and still see green, it might be time to seek expert help. Professional pool technicians have specialized tools and knowledge to tackle severe problems. Keep in mind that high Cyanuric acid and/or high calcium hardness are common contributors to these types of contaminations!
