There’s nothing more frustrating for a Phoenix pool owner than stepping outside to find your once crystal-clear pool has turned a murky shade of green. While green water is often caused by algae growth, chemical imbalance, or neglected maintenance, the good news is that it can be fixed. With the right process and professional help, a green pool can be restored to clean, safe, blue water.
Aqua Harmony Pools specializes in green to blue pool service in Phoenix, helping homeowners recover neglected pools and keep them healthy year-round. This guide explains how professionals restore green pools and why ongoing maintenance is essential to preventing future issues.
Phoenix’s hot, sunny climate creates ideal conditions for algae growth. Even pools with functioning equipment can turn green if maintenance slips. Common causes include:
• Algae growth due to warm water, sunlight, and low sanitizer levels
• Chemical imbalance from low chlorine, improper pH, or alkalinity issues
• Poor circulation caused by inefficient pumps or clogged filters
• Debris buildup such as leaves, dirt, and organic matter that feed algae
Identifying the root cause helps ensure the problem doesn’t return after restoration.
Before any treatment begins, professionals test the pool water to understand its condition. This includes checking:
• Chlorine levels
• pH
• Alkalinity
• Calcium hardness
• Cyanuric acid (stabilizer)
Balancing the water is critical. If chemistry is severely off, adding chlorine alone won’t solve the problem, and the pool will remain green.
All visible debris must be removed before shocking the pool. Professionals use:
• Pool skimmers
• Nets
• Pool vacuums
Removing debris eliminates nutrients algae rely on and allows chemicals to work more effectively while protecting filters from clogging.
Algae often clings to pool walls, floors, tiles, and steps. Professional service includes thorough brushing to:
• Scrub walls, steps, and tile lines
• Focus on corners, ladders, and light fixtures
• Loosen stubborn algae from surfaces
This step is essential because chlorine works best on algae that is no longer attached to surfaces.
Shocking the pool involves adding a high dose of chlorine or sanitizer to kill algae and bacteria. For heavily neglected pools:
• Super-chlorination may be required
• Shock treatments may be applied in stages
• Chemical levels are closely monitored and adjusted
This is the most critical step in turning a green pool blue and requires proper expertise to avoid damaging surfaces or equipment.
Once algae is killed, filtration removes dead algae and contaminants from the water:
• Pumps are run continuously for 24–48 hours
• Filters are backwashed or cleaned frequently
• Water flow is checked to ensure proper circulation
Without proper filtration, dead algae can remain suspended or settle back into the pool.
After the pool begins clearing, water chemistry is tested again:
• Chlorine levels are adjusted to safe swimming ranges
• pH and alkalinity are corrected
• Calcium hardness is balanced to protect surfaces and equipment
Balanced water is essential to prevent algae from returning.
Once the pool is restored, ongoing maintenance keeps it from turning green again. Preventive steps include:
• Weekly skimming, brushing, and vacuuming
• Testing water chemistry 1–2 times per week
• Running pumps 6–8 hours daily, adjusted seasonally
• Using algaecide as needed
• Keeping filters clean and functioning properly
Consistency is the key to long-term clarity.

Minor algae issues can sometimes be handled by homeowners, but a fully green pool often requires professional intervention. Aqua Harmony Pools provides green to blue pool service in Phoenix that includes:
• Comprehensive water testing and chemical balancing
• Complete algae removal and deep cleaning

Hiring professionals offers several advantages:
• Faster restoration timelines
• Safe and effective chemical handling
• Thorough cleaning of surfaces and equipment
• Long-term algae prevention strategies
• Peace of mind knowing the pool is safe to swim
In Phoenix’s extreme heat, professional service ensures faster, more reliable results.
