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. The longer you leave it, the more time consuming and costly it will be to bring your beautiful pool back to life.  To determine how much algae is in your pool, or in other words, how 'bad' it is, use the BioGuard Colour Diagnosis below.

The most effective way to remedy your pool is through a shock and algaecide treatment. We recommend a measured dose of BioGuard Burn Out Extreme supplemented with an algaecide.

To do this, follow the Shock Formula: one 600g bag of BioGuard Burn Out Extreme treats a 50,000 litre pool. Keep your filter and pump running for at least 10 hours during and after the treatment, waiting until it’s dark before administering so the sun doesn’t burn off any unstabilised chlorine.

It’s important to note that all shock treatments should be supplemented with an algaecide. By combining two active ingredients into one formula, 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!
