How to Remove Black Algae from a Swimming Pool in South Africa

Black algae is one of the most difficult pool problems faced by South African pool owners, especially during the warmer months.

Signs of black algae

• Dark black or dark green spots on pool walls

• Slimy patches that return after brushing

• Cloudy water even when chlorine levels seem correct

Why chlorine alone often doesn’t work

Black algae forms protective layers that make it resistant to normal chlorine treatments. A dedicated algae treatment is usually required.

Using Activator D™

Activator D™ is a chlorine-free monthly treatment designed to help control black and green algae in pools up to 50,000 litres.

Basic treatment steps

1. Brush the affected areas thoroughly.

2. Adjust the pool pH if necessary.

3. Add the recommended amount of Activator D™.

4. Run the pool pump for several hours.

5. Repeat brushing if heavy algae is present.

Preventing algae from returning

• Brush the pool weekly

• Keep the pump running regularly

• Remove leaves and debris promptly

• Use Activator D™ as part of your monthly maintenance routine
