How to fix a green pool

Apart from looking grim and uninviting, a green pool is unhealthy for you and your pool equipment.  It needs to be 'rescued' as soon as possible - you can DIY with easeor call us for assistance.  The most effective way to remedy your pool is through a shock and algaecide treatment, and following BioGuards simple 3-Step Program. In the first instance, we recommend a measured dose of BioGuard Burn Out Extreme supplemented with MSA Extreme is a double action attack – eradicating algae swiftly and successfully.

To determine how much algae is in your pool, use the BioGuard Colour Diagnosis below.


Light Green/Teal Coloured Water

This indicates a low level of algae and will require the basic shock formula above. Add one bag of BioGuard Burn Out Extreme to every 50,000L of pool water plus the addition of algaecide.

Green Or Dark Green

This generally signifies a medium amount of algae in the water. Requiring more than one treatment. Add two bags of BioGuard Burn Out Extreme to every 50,000L of pool water plus the addition of algaecide.

Black/Brown-Green Water

At this point, it would be recommended calling Pool Water Specialists for advice.  If you live on the Hibicsus Coast or Rodney district, we can come out and take a look. We'll will be able to advise you of the correct chemical dosage required or if the pool needs to be drained. NEVER drain a pool without seeking advice first - it can ‘pop’ out of the ground and be totally destroyed!

Water still looks unwell? Fear not – once the algae is destroyed, your water will have a cloudy, grey and blue appearance. To bring your pool back to its healthy best, run your pump and filter and introduce BioGuard Super Clear Clarifying Tabs. If pain persists, call us again on 027 557 5072 for further assistance.

Remember, all of this can be avoided by following our 3 Step Program; the most cost-effective way to keep your pool healthy, sparkling clear and free of algae!
