Why Phoenix Pools Turn Green — And How We Fix It
A green pool is one of the most common problems pool owners in Phoenix face — and one of the most urgent. Green water means algae has taken over, and algae is more than just unsightly. It creates a breeding ground for bacteria, makes surfaces dangerously slippery, and can cause serious damage to your pool's plaster, equipment, and filtration system if left untreated.
In Arizona, a pool can go from clear to green in as little as 24–48 hours during summer. Temperatures above 100°F combined with intense UV exposure burns through chlorine at an extreme rate. Miss one service visit, have a pump issue, or get hit by a haboob — and your chemistry can collapse fast.
Roadrunner Pool Service has been restoring green pools across the Phoenix Valley for over 24 years. We know exactly how to assess the severity, apply the right treatment, and get your water back to crystal clear — and we'll make sure it stays that way.
KNOW THE SIGNS
How Bad Is Your Green Pool?
Not all green pools are the same. The severity determines the treatment approach. Here's how to gauge where your pool stands — and what it means for the cleanup process.
Light Green
Water is slightly green or teal but you can still see the bottom. This is early-stage algae — the most treatable scenario. A shock treatment, brush, and chemical balance correction typically resolves this within 3–5 days.
Dark Green
Water is a deep green and you can't see the pool floor. Algae has fully colonized the water. This requires aggressive shock treatment, multiple brushings, filtration cycling, and several follow-up visits. Typical timeline is 5–10 days.
Black / Swamp
Water is black, brown, or has been neglected for an extended period. In these cases a chemical treatment alone may not be sufficient — an acid wash may be required to strip algae staining from the plaster. Our technicians will assess and advise.
OUR PROCESS
How We Clean Up a Green Pool
Every green pool cleanup follows a systematic process to eliminate algae completely and restore safe, balanced water chemistry.
Water Assessment
We test your current water chemistry — pH, alkalinity, chlorine, stabilizer — to understand exactly how far out of balance things are and determine the correct treatment approach.
Shock Treatment
We apply a heavy-duty chlorine shock treatment calibrated to your pool's volume and algae severity. This begins the process of killing the algae bloom throughout the water.
Brushing
We thoroughly brush all pool walls, steps, and floor surfaces to dislodge algae colonies attached to the plaster and force them into the water where the chemicals can destroy them.
Filter Running
Your filter needs to run continuously during the cleanup process to remove dead algae from the water. We check filter pressure and backwash or clean as needed to maintain optimal filtration.
Follow-Up Visits
Green pool cleanup isn't a one-visit job. We return to re-test, re-treat, vacuum dead algae off the floor, and continue the process until the water is completely clear and chemistry is fully balanced.
Prevention Plan
Once your pool is clear, we recommend a regular maintenance schedule to prevent it from happening again. A weekly service plan is the best insurance against another green pool situation in Arizona's climate.
WHY CALL A PROFESSIONAL
Why DIY Green Pool Treatment Usually Fails
Every summer, Phoenix pool owners pour bags of shock into green pools and wait — only to watch the water turn cloudy white, then green again a week later. Here's why that happens and why professional treatment works better:
Wrong chemical ratios
Without testing, you're guessing on dosage. Too little and the algae survives. Too much and you create a different chemical imbalance that's also harmful.
Skipping the brushing
Algae clings to surfaces. Chemicals in the water alone won't reach algae colonies attached to walls and the floor — it must be physically dislodged through thorough brushing.
Filter issues go unnoticed
A clogged or damaged filter can't remove dead algae fast enough. If the filter isn't working properly during cleanup, the water stays cloudy and algae can re-establish.
Professional treatment gets it right
Our technicians test first, apply the right treatment at the right dosage, brush thoroughly, and follow up until the job is completely done — not just until it looks better.
