Nothing Ruins Summer Faster Than a Green Pool
You've been keeping up with your pool all season, and then almost overnight the water turns green.
Green pool water is one of the most common problems Arizona pool owners face during July. Fortunately, it's also one of the easiest to prevent when you understand what's happening.
What Causes Green Pool Water?
In most cases, green water is caused by algae.
Algae thrive when:
• Chlorine levels fall too low
• Water circulation is poor
• Filters are dirty
• High temperatures accelerate algae growth
• Heavy monsoon storms introduce contaminants
Arizona's combination of extreme heat and intense sunlight creates ideal conditions for algae if your pool chemistry isn't properly maintained.
Signs Algae Is Starting
Watch for these early warning signs:
• Water beginning to look dull
• Slight green tint
• Slippery pool walls
• Increased chlorine demand
• Small green patches on steps or corners
Addressing algae early saves both time and money.
How to Prevent a Green Pool
Maintain Proper Chlorine Levels
Never let chlorine remain below the recommended range.
During extreme heat, your pool may require additional chlorine to stay protected.
Brush Weekly
Algae often begin growing in areas with poor circulation.
Regular brushing removes algae before it becomes visible.
Keep Your Filter Clean
Your filter captures microscopic contaminants that feed algae.
Cleaning or backwashing on schedule improves water clarity and sanitizer effectiveness.
Shock After Heavy Pool Use
Birthday parties, holiday gatherings, and weekends introduce oils, sunscreen, sweat, and organic contaminants.
A weekly shock treatment helps restore water quality.
Test Water Frequently
Water chemistry can change quickly during July.
Testing several times each week allows you to make small corrections before major issues develop.
What If Your Pool Is Already Green?
If your water has already turned green:
- Test your water.
- Balance the pH.
- Add the appropriate shock treatment.
- Brush the entire pool thoroughly.
- Run your filtration system continuously until the water clears.
- Clean or backwash your filter as needed.
