Green Pool Water in Dubai? We fix it — fast.
From dull green to swim-ready clear. Hello Landscaping & Pools LLC treats green, cloudy and algae-infested swimming pools across Dubai with professional shock treatment, filtration cleaning and water balancing — usually within 24–48 hours.
Signs your swimming pool water needs treatment
Green swimming pool water rarely happens overnight. These are the earliest signals that algae growth and poor pool water chemistry are taking hold — before the water turns fully green or murky.
Cloudy or murky water
Low water clarity is often the first symptom of a chlorine or filtration issue before algae fully blooms.
Visible green tint
A green cast in the water usually means active green algae growth or a metal-related discoloration.
Slippery pool floor
A slick film on steps or the pool floor is a strong indicator of algae spores colonising surfaces.
Low or zero free chlorine
Testing shows little to no free chlorine, meaning the sanitizer can no longer control contamination.
Why does swimming pool water turn green in Dubai?
Dubai's intense heat and sun accelerate algae growth far faster than in cooler climates. Once free chlorine drops and pool water chemistry drifts out of range, algae spores multiply within hours, turning clear water green and cloudy.
Depleted free chlorine
When chlorine levels fall, the pool loses its ability to kill algae and bacteria, allowing green algae to spread unchecked.
Unbalanced pH & alkalinity
High pH and low total alkalinity reduce chlorine's sanitizing power, even when chlorine is added regularly.
Weak pool filtration & circulation
A dirty pool filter or short pump run-times let algae spores and debris recirculate instead of being trapped.
Heat, sunlight & contamination
UV exposure burns off chlorine faster, while heavy pool use, dust and organic debris feed algae growth.
How we turn green pool water crystal clear
A structured, tested process — not guesswork. Every green pool water treatment in Dubai follows these four stages for reliable, lasting results.
Test pool water chemistry
We test free chlorine, pH, total alkalinity and stabiliser levels to diagnose the exact cause of the green pool water.
Pool shock treatment
A calculated chlorine shock treatment eliminates algae spores and restores an effective sanitizer level throughout the pool.
Brush, vacuum & filter clean
We brush algae from walls and floor, vacuum debris, and deep-clean the pool filter and pump for proper circulation.
Balance & final water test
Chlorine, pH and alkalinity are fine-tuned and retested until the water reads crystal clear and swim-safe.
Fixing a green salt water pool needs a different check-list
Salt water pools rely on a salt chlorinator cell to generate chlorine. When that cell fails, gets scaled up, or the salinity level drifts out of range, chlorine production drops — and the pool turns green even though it looks "self-cleaning."
- Salt cell and chlorinator output inspection
- Salinity level testing and correction
- Manual chlorine shock treatment as a booster
- Full pool filtration system cleaning
Still green or cloudy after shocking your pool?
DIY shock treatments often fall short. Here's why pool water sometimes stays green or cloudy even after chlorine is added — and how our team resolves each cause.
Filtration wasn't run long enough
+Dead algae needs continuous filtration for 24–72 hours to be fully removed. Turning the pump off too soon leaves the water hazy.
The chlorine dose was too low
+Heavily contaminated water needs a stronger, calculated shock dose — under-dosing only suppresses algae temporarily.
pH and alkalinity were still off
+High pH neutralises chlorine's effectiveness, so even a strong shock treatment won't fully clear the water.
The pool filter itself is dirty
+A clogged or contaminated filter recirculates fine algae particles instead of trapping them, keeping water cloudy.

Green pool water — common questions
Straight answers to the questions Dubai pool owners ask us most.
Why does my swimming pool water turn green?
+Pool water turns green mainly due to algae growth caused by low free chlorine, imbalanced pH or alkalinity, and poor filtration. Dubai's heat speeds up algae spore multiplication, and metals like copper or iron can also cause a green tint.
How long does it take to fix a green pool in Dubai?
+Most green pools clear within 24 to 48 hours after professional chlorine shock treatment, filter cleaning and water balancing. Heavily contaminated pools with thick algae growth can take 3 to 4 days.
Why is my pool still green or cloudy after shocking it?
+Usually because the filtration wasn't run long enough to clear dead algae, the chlorine dose was too low, pH and alkalinity were unbalanced, or the pool filter itself is dirty and recirculating contaminated water.
Can a green salt water pool be fixed the same way?
+Mostly yes, but a salt water pool also needs the salt cell and salinity level checked, since a faulty salt chlorinator is a common root cause of green water in salt systems.
Is it safe to swim in a green pool?
+No. Green water signals low sanitizer levels and active algae growth, which can carry bacteria and irritate skin, eyes and ears. Wait until the water is professionally treated and tests clear.
