Green to Clean Lake Havasu, AZ

What Causes a Pool to Turn Green?

The vivid green color of a neglected or out-of-balance pool is caused primarily by algae growth, which thrives in warm, untreated, or under-filtered water. In Lake Havasu’s hot climate, algae can spread rapidly—sometimes overnight—if sanitization or circulation lapses even briefly.

Common causes of green pool water include:

• Low chlorine or sanitizer levels
• Broken or poorly functioning pool equipment
• Imbalanced water chemistry (pH, alkalinity, calcium hardness)
• Ineffective or clogged filtration
• High phosphates, which fuel algae growth
• Debris build-up from dust, wind, and plant matter
• Standing water or prolonged inactivity, such as vacation homes left untreated

Regardless of the cause, a green pool is a problem that requires professional attention. Attempting to fix it with simple “shock” treatments or DIY methods can often make the situation worse, especially when the root issues aren’t addressed.

The Dangers of a Green Pool

While it may seem like a cosmetic issue, green pool water poses real risks:

• Health Hazards: Algae can harbor harmful bacteria like E. coli and can lead to skin irritation, ear infections, or gastrointestinal illness.
• Slip and Fall Risks: Algae can make pool steps, walls, and floors extremely slippery.
• Structural Damage: Long-term algae infestations can stain plaster, corrode surfaces, and clog filtration systems.
• Equipment Stress: Trying to operate pumps and filters in severely green water can lead to breakdowns or overworking your system.

It’s always best to address green pool conditions quickly—and professionally—before they lead to more serious or expensive problems.

JM Pool Service’s Green Pool Cleaning Process

We don’t just make your water look better—we restore the entire pool to balanced, swim-ready condition. Our proven process is customized based on how green or black the water has become, the size of your pool, and the condition of your equipment and surfaces.

Step 1: Full System Evaluation

We begin with a thorough inspection of your pool’s current state. This includes checking sanitizer levels, algae presence, clarity, pump operation, filtration functionality, and chemical balance.

Step 2: Equipment Check

Our technicians assess whether your filter, pump, and circulation system are operational. If repairs are needed, we’ll provide expert recommendations before proceeding with a full clean.

Step 3: Debris Removal

We remove leaves, debris, and any large organic material that may be contributing to the contamination. This allows chemical treatments to work more effectively.

Step 4: Water Testing and Balancing

Before shocking the pool, we measure pH, alkalinity, and other factors. If your pool chemistry is way out of range, chlorine shock won’t be effective. We balance the water to ensure proper chemical reactions.

Step 5: Shock and Algaecide Treatment

Using professional-grade treatments, we administer a high dose of chlorine (shock) and specialized algaecides to kill off all algae strains present—green, mustard, or black.

Step 6: Brushing and Vacuuming

Once the algae has been neutralized, we scrub the pool walls, steps, and floor to remove remaining residues and biofilm. Vacuuming is then performed to extract dead algae and debris.

Step 7: Filtration and Circulation Optimization

We clean or backwash your filters and monitor your pump and circulation system to ensure maximum flow and filtration. If filter media (sand, DE, or cartridges) are damaged or overly clogged, we’ll recommend replacement.

Step 8: Follow-Up Treatments and Clarity Monitoring

Depending on how severe the infestation was, multiple treatments may be required over a few days. We return to re-test and adjust chemical levels as needed to bring your water back into clear, balanced, swim-ready condition.

When Draining the Pool Is Necessary

In some severe cases—such as when algae has gone unchecked for months, the water is nearly black, or stains have penetrated the plaster—it may be necessary to drain and acid wash the pool entirely. Our experts will advise if this is the best course of action and handle the process safely and in compliance with Lake Havasu’s local water disposal ordinances.

Green Pool Recovery: What to Expect

While every pool is different, most green pool cleanings take 2 to 5 days to complete, depending on the severity of the algae bloom and the condition of the pool’s circulation system. Some pools may recover quickly with a single treatment; others require a staged approach with ongoing testing and adjustments.

We keep you informed throughout the process so you know what to expect at each step.

Preventing Future Algae Growth

Once your pool is clean again, we’ll help ensure it stays that way. As part of our green pool cleaning service, we offer post-recovery guidance and maintenance support, including:

• Scheduled weekly pool service to keep chemicals and circulation in balance
• Filter and pump maintenance to ensure proper operation
• Phosphate control to prevent future algae food sources
• Pool cover and cleaning recommendations to reduce organic debris
• Seasonal adjustments based on Lake Havasu’s extreme heat cycles

We also offer automation upgrades and salt system installation if you’re looking for a more hands-off way to manage long-term pool care.
