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