Emergency Pool Recovery Protocol

Pool emergencies require systematic treatment in the correct order. Rushing the process or skipping steps increases recovery time.

Initial Assessment

• Close pool to all users immediately.
• Test: FC, TC, CC, pH, TA, CYA, and note water colour and clarity.
• Identify likely cause: pump failure, feeder empty, high CYA, extended period without service.
• Photograph current condition (for liability records).
• Verify pump is running and filter is operating at normal pressure.

Green Pool Recovery (Algae Bloom)

• Step 1: Lower pH to 7.2 using muriatic acid — this maximises chlorine activity.
• Step 2: Brush all pool surfaces vigorously to break algae biofilm.
• Step 3: Add shock to achieve 30 ppm FC — use the shock calculator for exact dose.
• Step 4: Run filter 24 hours continuously.
• Step 5: Test FC every 4–6 hours. If below 10 ppm, add more chlorine to maintain 10+ ppm.
• Step 6: When water turns grey-white, vacuum dead algae to waste. Backwash filter.
• Step 7: Continue filtering until FC drops naturally to 5 ppm or below.
• Step 8: Run full balance test and correct all parameters.
• Step 9: Photograph recovered water and log the event.
• Step 10: Identify root cause and adjust maintenance to prevent recurrence.

Moderately Compromised Water (Cloudy, High CC)

• Step 1: Test and record all parameters.
• Step 2: Adjust pH to 7.2–7.4.
• Step 3: Shock to 10 ppm FC.
• Step 4: Add clarifier after chemistry is corrected.
• Step 5: Run filter 24 hours.
• Step 6: Retest and balance all parameters.

Notes

• Never allow guests into the pool during recovery.
• Log the event and all corrective actions.
• If recovery takes more than 72 hours, consider whether a partial drain is needed.
