Green Pool Guide

Why is my pool green — and how do I fix it fast?

A green pool is almost always caused by algae thriving in unbalanced water. South African summers, intense UV, and warm temperatures make pools especially vulnerable.

Common causes

  • Poor water circulation
  • Heavy rain introducing contaminants
  • Neglecting monthly treatment
  • Unbalanced water pH
  • Lightning storms

How to clear a green pool with Activator-D™

  1. Test and balance your water (pH 7.2–7.6)
  2. Brush walls and floor thoroughly
  3. Apply Activator-D™ — it eliminates algae at the root without the need for separate shock or chlorine treatments
  4. Run your pump for 24 hours
  5. Vacuum dead algae to waste

Activator-D™ is a once-a-month treatment that replaces shock and chlorine — keeping algae from ever returning. No daily dosing, no hassle.

Turn Your Green Pool Crystal Clear with Activator-D

A green swimming pool is usually caused by algae growing in the water after rain, heat, poor circulation, or low sanitizer levels. The good news is that you don't always need large amounts of chlorine to restore your pool.

Signs your pool has green algae

  • Water looks green or cloudy.

  • Pool walls feel slippery.

  • Green algae appears on steps, corners or the floor.

How to use Activator-D

  1. Backwash your filter before treatment.

  2. Pour the Activator-D Powder directly into the skimmer/weir.

  3. Pour the Activator-D Liquid into the skimmer/weir immediately afterwards.

  4. Run the pump continuously for 8–12 hours.

  5. Brush stubborn algae if necessary and allow the filter to remove dead algae.

Tips for best results

  • Clean the skimmer basket before treatment.

  • Run the pump overnight if possible.

  • Vacuum the pool after treatment if dead algae settles on the floor.

Most pools begin clearing within 24–48 hours depending on the severity of the algae.

Activator-D is a chlorine-free monthly treatment designed to help control black and green algae while restoring sparkle to your pool.
