Shamal dust and the 48-hour algae window
The response window is short. Within a day of a major dust event the pool should be skimmed, the walls and floor brushed to lift settled dust before it binds to surfaces, the skimmer and pump baskets emptied, and the filter run extended. A preventive shock dose after a bad storm is cheap insurance; a green-to-clean recovery a week later is a multi-visit job involving heavy chlorination, flocculant, vacuuming to waste and sometimes a filter media change.
Owners who travel in summer are the classic victims here, because a storm hits, nobody brushes the pool, and the villa is reoccupied three weeks later to opaque green water. If you will be away during peak shamal months, keep the maintenance contract running rather than pausing it; rebooking the same vendor for an extra post-storm visit takes a moment in the tamam app, and the technician who already knows your pump room will move faster than a stranger.
