"We came back from December holidays to a pool the colour of pea soup. I was sure it needed draining, Rapid had it sparkling in five days without emptying a drop. Genuinely amazed."

Green Pool Recovery in Johannesburg, Crystal-Clear in About a Week
Algae bloom, broken pump or a neglected pool you've just inherited? We diagnose why your water went green and bring it back to sparkling, usually within a week. Fast, fixed-price green pool recovery across Sandton, Randburg, Midrand, Roodepoort and the greater Johannesburg region.
From swamp to swim-ready
Turn that green pool blue again
Staring at a murky, swamp-green pool is enough to make anyone want to drain it and start over, but you almost never need to. Our green pool recovery Johannesburg service tackles the algae at the source: we test the water, knock back the bloom with the right treatment and run your system properly until the green is gone and the floor is visible again.
Whether it's a holiday that got away from you, a pump that quietly died, or a neglected pool that came with the house, we've cleared hundreds of them across Johannesburg and beyond. Send us a photo, tell us roughly how green it is, and we'll tell you honestly how long it'll take and what it'll cost. Once the water is clear, our regular pool cleaning service keeps the surfaces and water sparkling between visits.
- No draining in most cases, we recover green pools with chemistry and filtration.
- Usually clear within a week, many light blooms in just a few days.
- Fixed price upfront, assessed and quoted before any work begins.
- Stays clear afterwards, we can keep it that way with a maintenance plan.
Why pools go green in the first place
Green water is algae, and algae only thrives when something has slipped. Usually it's the chemistry drifting out of range, chlorine drops, pH climbs, or the pump and filter not circulating the water the way they should. Add Gauteng's warm days and a single missed week can be enough to tip a clear pool into a bloom.
The other common culprits are simple: a pool left to its own devices over a long holiday, or one that's been standing for weeks before new owners move into a house. Whatever the cause, we find it and fix it, clearing the green and stopping it from coming straight back. If the bloom turns out to be down to a broken pump or cracked pipework, our wider pool repairs team gets the equipment running again so the recovery holds.
Just bought a house with a green pool? We specialise in rescuing inherited and long-neglected pools, book an assessment and we'll have it swim-ready before your first weekend braai.
How we bring a green pool back
- Test & diagnose, we check the water and equipment to find why it went green.
- Shock & super-chlorinate, a strong dose knocks the algae bloom down hard.
- Balance the chemistry, pH, alkalinity and stabiliser corrected to hold the kill.
- Run filtration hard, the pump and filter cycle out the dead, suspended algae.
- Vacuum to waste, settled debris is vacuumed out rather than back through the filter.
- Drain & acid wash if needed, only for severe cases the chemistry can't recover.

Green pool recovery questions, answered
Why does a swimming pool turn green?
A pool turns green when algae take hold, and that almost always traces back to one of a few things: chlorine and pH drifting out of range, a pump or filter that has stopped circulating the water properly, or simple neglect, a pool left unattended after a holiday or one you've inherited when buying a house. Warm Gauteng weather then lets the algae bloom fast.
Can a green pool be saved without draining it?
In the large majority of cases, yes. By super-chlorinating, correcting the chemistry, running filtration hard and vacuuming the dead algae to waste, we recover most green pools without emptying them. We only recommend a drain and acid wash for severely neglected pools where the surface is heavily stained or the water is beyond rebalancing.
How long does it take to clear a green pool?
Most pools we treat go from green to crystal-clear within about a week. A light bloom can clear in two to three days, while a badly neglected, dark-green pool full of debris may take a little longer or need a drain and acid wash. We give you a realistic timeline after our first visit.
How much does green pool recovery cost in Johannesburg?
It depends on how green the pool is, its size and whether the equipment is working. A standard chemical recovery costs far less than a drain and acid wash. We assess the pool, explain exactly what it needs and quote a fixed price before we start, so there are no surprises.
Will my pool turn green again, and do you offer maintenance after recovery?
Not if it's looked after. Green pools come back when chemistry slips or the pump and filter aren't run consistently. We hand the pool back balanced and clear, and most clients move onto a weekly, fortnightly or monthly maintenance plan, covering chemistry, cleaning and equipment checks, so it simply never happens again.
Which areas do you cover?
Johannesburg, Sandton, Randburg, Midrand, Roodepoort and surrounding suburbs, plus the East Rand and Pretoria region. See all service areas.
Green pools rescued across Gauteng
"Our new house came with a black, neglected pool we couldn't even see the bottom of. They diagnosed a dead pump, sorted it and recovered the water. Now on their monthly plan and it's never gone green since."
