A green pool won’t clear on its own — the longer algae sits, the more it stains surfaces and strains your equipment. Get a fast assessment and treatment plan.

Expert Green Pool Recovery by Pool Quest

Green water happens when algae multiplies faster than your sanitiser can control it — usually from low or inconsistent chlorine, a pH or alkalinity imbalance, poor filtration, or heavy rain diluting your chemicals. Once algae takes hold, a pool can turn green within 24 to 48 hours. Pool Quest diagnoses the exact cause before treating it, so the problem doesn’t come back within days.

Why Fast Green Pool Treatment Matters

The longer algae sits, the harder and more expensive it is to remove. Left untreated, green water can stain marbelite, fibreglass, and tile surfaces, clog and strain filters and pumps, and make the pool unsafe to swim in. Most green pools can be recovered without draining if treated promptly.

What’s Included in Our Green Pool Recovery

Every green pool is different, so we start with a diagnosis, not a guess. Our recovery service includes:

Water Testing & Diagnosis

We test chlorine, pH, alkalinity, and stabiliser to identify exactly what let the algae take hold.

Shock Treatment

A calculated chlorine shock kills active algae without wasting chemicals or over-dosing your water.

Algaecide Application

For stubborn or recurring blooms, we apply a targeted algaecide alongside the shock treatment.

Filtration & Circulation Run

We run your filter continuously to clear dead algae from the water instead of letting it settle.

Manual Brushing & Vacuuming

Walls and floors are brushed to loosen algae still clinging to surfaces, then vacuumed out.

Filter Cleaning

We backwash or clean your filter mid-treatment so it doesn’t clog under the extra algae load.

Follow-Up Water Test

We retest once the water clears to confirm your chemistry is stable before we leave.

How Our Green Pool Recovery Process Works

Recovery time depends on how far the algae bloom has progressed, but most pools follow the same process:

  • Assessment

    We test the water and inspect equipment to find the root cause of the bloom.

  • Shock & Treat

    We dose chlorine and algaecide to kill active algae fast.

  • Filter & Circulate

    Continuous filtration clears dead algae from the water over 24–48 hours.

  • Brush & Vacuum

    Remaining algae on surfaces is manually removed.

  • Rebalance

    Chlorine, pH, and alkalinity are retested and adjusted until stable.

  • Prevention Plan

    We recommend a maintenance schedule so it doesn’t happen again.

Most green pools clear within 24 to 72 hours of treatment, depending on how severe the bloom is and how well filtration is running going in.

Preventing Green Water After Treatment

Once your pool is clear, regular maintenance is what keeps it that way. Consistent routine pool cleaning and chemical checks catch small imbalances before they turn into another algae bloom, especially after heavy rain or a spell without a service visit. If your chlorinator has been underperforming, that’s often the root cause worth fixing first.

FAQs – Green Pool Treatment

1. How long does it take to fix a green pool?

Most pools clear within 24 to 72 hours after shock treatment, depending on how severe the algae bloom is and how well your filter is running.

Usually not. Most green pools recover through shock treatment, filtration, and manual cleaning. Draining is only needed for severe, long-neglected cases.

Heavy rain dilutes chlorine and can wash organic debris into the pool, both of which give algae the opening it needs to multiply.

Not if chemistry is kept stable afterward. We recommend a maintenance check within a week of treatment to confirm chlorine and pH have held.

Yes. We treat both saltwater and chlorine pools, adjusting the approach to protect your salt cell and equipment.

No — wait until chlorine levels return to a safe range and the water has fully cleared before swimming.

Yes. We provide urgent call-outs across Johannesburg for pools that have turned green suddenly.
