Why Does Your Swimming Pool Turn Green in Costa Blanca?

Owning a swimming pool in sunny Costa Blanca is a dream for many homeowners. However, one common problem that can ruin your pool experience is green water. Understanding why your pool turns green and how to prevent it is key to enjoying crystal-clear water all year round.

1. Algae Growth – The Main Culprit

The most frequent reason for a green pool is algae growth. The warm and sunny climate of Costa Blanca creates perfect conditions for algae to thrive. Without proper swimming pool cleaning and regular chemical maintenance, algae can multiply rapidly, giving your pool that unwanted green hue.

2. Imbalanced Water Chemistry

Maintaining the right chemical balance is essential for Costa Blanca pool maintenance. Low chlorine levels, high pH, or low alkalinity allow algae and bacteria to grow. Regularly testing and adjusting your pool’s chemical levels keeps the water safe and clear.

3. Insufficient Filtration During Hot Months

In the summer months, pool pumps need to run longer than many owners expect.

In areas like Torrevieja and Orihuela Costa, high temperatures mean filtration systems often need to operate 8–12 hours per day.

Poor circulation creates “dead zones” where algae can grow unnoticed.

4. Dust, Sand and Storms

Southern Spain occasionally experiences dusty or windy conditions that carry fine particles into your pool.

This dust:

• Introduces organic material

• Increases chlorine demand

• Feeds algae growth

After storms or dusty days, extra swimming pool cleaning and chemical checks are highly recommended.

5. High Pool Usage in Holiday Homes

Many properties in Jacarilla, Benijófar and La Marina are holiday homes or rental villas.

Higher bather load means:

• Faster chlorine depletion

• Increased contamination

• Greater need for regular pool service

Consistent professional maintenance prevents small issues from becoming expensive problems.

How to Prevent Green Pool Water

If you want to avoid algae and green water, follow these steps:

✔ Test water regularly
✔ Maintain correct chlorine and pH levels
✔ Run the filtration system daily in summer
✔ Brush walls and vacuum weekly
✔ Schedule reliable pool cleaning service

Final Thoughts

Green pool water is usually caused by algae growth, chemical imbalance, or insufficient filtration.

Whether you need pool maintenance in Torrevieja, pool cleaning in La Marina, or pool service in Orihuela Costa, regular professional care ensures your swimming pool stays safe, clean, and ready to enjoy.

Troubleshooting Pool Pump Problems in Costa Blanca – Common Causes & Solutions

Your pool pump is the heart of your swimming pool, keeping water clean, circulating chemicals, and ensuring a healthy swimming environment. In Costa Blanca, with our hot summers and occasional Saharan dust, pumps can sometimes develop problems faster than in other regions. This guide will help you identify common issues and know when to call a professional.

Common Pool Pump Problems

1. Pump is not turning on

• Possible causes: power supply issues, tripped breaker, clogged motor, or worn-out capacitor.

• Quick check: Make sure the pump is plugged in and the breaker hasn’t tripped. Inspect for visible obstructions.

• Tip for Costa Blanca: Summer heat can stress the motor. Never attempt electrical repairs yourself—call a professional if unsure.

2. Pump is making strange noises

• Common sounds: grinding, rattling, or buzzing.

• Causes: debris in the pump basket, air trapped in the system, or worn bearings.

• Local tip: With the frequent winds and dust in Costa Blanca, check the skimmer and pump basket regularly. Cleaning them can prevent many noises.

3. Low water pressure or poor circulation

• Causes: clogged filter, closed valves, or air leaks in the suction line.

• What you can do: Check all valves, clean the skimmer basket, and backwash the filter if necessary.

• When to call us: Persistent low pressure may indicate a pump or filter issue needing professional attention.

4. Leaks around the pump

• Signs: water pooling around the base or damp motor.

• Causes: loose connections, worn seals, or cracks in the pump housing.

• Local advice: Coastal humidity in Costa Blanca can accelerate wear. Don’t ignore leaks—they can lead to bigger problems.

5. Pump runs but doesn’t circulate water properly

• Possible reasons: air in the system, blocked pipes, or impeller damage.

• Quick fix: Bleed the air from the pump and check the basket for blockages.

• Pro tip: If circulation remains poor, call a professional to avoid motor burnout.
