How do I clean a green swimming pool in Nairobi?

A green swimming pool indicates an algae bloom — typically caused by insufficient chlorine levels combined with warm Nairobi temperatures. Recovery is possible with prompt treatment.

Why Pools Turn Green in Nairobi

  • Chlorine depletion — Nairobi’s intense UV radiation breaks down chlorine rapidly; outdoor pools need significantly more than indoor pools
  • Filter failure or neglect — a blocked filter cannot maintain water clarity
  • pH imbalance — if pH rises above 7.6, chlorine becomes largely ineffective
  • Heavy rains — dilute chemical levels and introduce organic matter and nutrients that feed algae

Green Pool Recovery Process

  1. Test the water – Check pH, chlorine, alkalinity, and cyanuric acid levels
  2. Adjust pH to 7.2 – This is the optimal level for shock treatment effectiveness
  3. Shock the pool – Add 3–5x the normal chlorine dose (calcium hypochlorite or liquid chlorine); treat at dusk as UV breaks chlorine down instantly
  4. Run the filter continuously – For 24–48 hours while treating
  5. Brush pool walls and floor – Dislodge algae clinging to surfaces for the filter to remove
  6. Vacuum to waste – Once algae dies (turns grey/white), vacuum debris directly to waste, not through the filter
  7. Re-balance chemicals – Return all levels to optimal ranges
