How to Recover Your Pool After a Jeddah Sandstorm: Step-by-Step Emergency Guide

Anyone who owns a villa with an outdoor pool in Jeddah knows the feeling of waking up after a desert wind event or dust storm (haboob) to find what was once a sparkling turquoise pool transformed into a murky, brown mud pit.

Fine desert silt carried from the surrounding Hijaz region carries high organic matter, phosphates, and minerals. If treated incorrectly, this dust can quickly ruin filter media, burn out pump impellers, and turn into an emerald-green algae catastrophe.

Follow our field-tested 6-step recovery protocol used by our emergency technicians across Jeddah.

The 6-Step Sandstorm Recovery Protocol

Step 1: Skim Floating Debris & Empty Baskets First

Before running any chemicals, use a deep leaf rake net to scoop out floating leaves, palm fronds, and heavy surface debris. Empty the skimmer weir baskets and the pump hair-and-lint strainer basket to ensure unobstructed water flow.

Step 2: Test and Balance pH & Alkalinity

Desert dust in Saudi Arabia is highly alkaline. It often spikes pool pH above 8.0, which renders chlorine virtually ineffective.

• Test water pH with a reliable drop kit or digital photometer.
• Add dry acid (sodium bisulfate) or muriatic acid to bring the pH down into the optimal range of 7.2 to 7.4.

Step 3: Dose with Pool Flocculant (For Heavy Silt)

If you cannot see the bottom of the shallow end, a standard pool clarifier is not strong enough. You need an aluminum-sulfate-based Pool Flocculant:

1. Turn the multi-port valve to RECIRCULATE (bypassing the filter tank).
2. Broadcast the recommended dose of flocculant evenly across the pool surface.
3. Run the pump on recirculate for 2 hours to mix thoroughly.
4. Turn the pump completely OFF for 12 to 24 hours. Keep the pool undisturbed. All suspended silt will clump together and sink to the bottom like a heavy grey-brown blanket.

Step 4: Vacuum Directly to WASTE (The Golden Rule)

This is the step most pool owners get wrong.

• Set your multi-port valve to WASTE.
• Slowly, methodically vacuum the settled silt off the floor directly out through the backwash drain line.
• Note: This will lower your pool water level by a few inches, so keep a garden hose running in the skimmer to prevent losing suction.
• Never vacuum flocculated silt through your sand or cartridge filter!

Step 5: Chlorine Shock Treatment

Once the heavy silt is removed, test chlorine. The organic load introduced by the dust storm will have depleted all free chlorine.

• Dose with shock chlorine (calcium hypochlorite or sodium hypochlorite) to achieve 10 ppm free chlorine.
• Add a preventive dose of polyquat 60 algaecide to stop dormant algae spores from germinating.

Step 6: Deep Backwash and 24-Hour Continuous Filtration

Turn the valve back to FILTER and run the pump continuously for 24 to 48 hours. Monitor the filter pressure gauge; as remaining fine particles are trapped, pressure will climb. Perform a 3-minute backwash and 30-second rinse whenever pressure rises 8–10 PSI above baseline.
