Green Pool Recovery
Same-day response for green pool emergencies across Auckland. From $500, no obligation quote.
If your pool has turned green, the first thing to know is that it's fixable — but it's not a one-visit job, and anyone who tells you otherwise is setting you up to be disappointed a week later. A green pool is typically fully recovered in around 4 visits, though it can be fewer or more depending on how far gone it is when we start.
What causes it
Pools turn green when algae takes hold — usually after a stretch of low chlorine, unbalanced pH, warm weather, or a pool that's been left unattended for a while (a common one: coming back from a holiday to find the pool's turned on you). High phosphate levels can also feed algae growth even when chlorine looks okay, since phosphates are a food source algae thrives on. Once algae establishes, it doesn't clear with a single shock dose; the water needs to be treated, tested, and re-treated in stages as the chemistry stabilises and the dead algae gets filtered out.
How it works
First visit is assessment and stabilisation: testing the water, identifying how bad the imbalance is, and starting the treatment process. From there it's follow-up visits — checking the chemistry, adjusting as needed, and continuing treatment — until the water is genuinely clear and balanced, not just clear enough to look fine for a day before turning again. That's the standard that matters: the job's done when the pool is actually recovered, not when it's visually presentable for one afternoon. Draining and refilling is rarely necessary and often makes things worse — it's expensive and can damage a plaster or concrete surface if drained incorrectly, and a proper shock-and-filter cycle usually clears it without needing to start from scratch.
Why it's treated as urgent
Cooper's background is aircraft engineering and the fire service — both fields where you don't declare something fixed until it's actually verified fixed, and where a call marked urgent gets treated like one. A green pool gets the same treatment: it's queued ahead of routine visits, not behind them. It's also worth treating as urgent rather than cosmetic — algae blooms are often paired with low or zero sanitiser, meaning bacteria can be present too, not just algae. Wait until the water is fully cleared and chemically balanced, confirmed by testing, before swimming again.


What that's looked like in practice
One recent example: Ying's pool turned green, and it took multiple visits to properly recover — not a single dose of chemicals with fingers crossed. Every time a visit needed to move, she was told in advance rather than left guessing. That's the standard applied to every green pool job, not just this one.
“Cooper helped us with a green pool recovery and responded incredibly quickly. He visited multiple times, was very thorough, and clearly took the job seriously. Communication was excellent — when he couldn't make it, he let us know in advance, which we really appreciated. Very responsible and reliable service.”
