A green pool in Marrakech is not a disaster, it is a recovery job: shock chlorine dosed to the real volume, algaecide, flocculant, continuous filtration and vacuuming of the deposits — the water turns clear again within 24 to 48 hours in the vast majority of cases, without draining. At 45 °C, an untreated pool turns within two days; every day of waiting makes the recovery longer. For rental villas, we treat with priority before check-ins: green water on arrival day is a guaranteed one-star review.
45 °C summers: In Marrakech, the water of an untreated pool turns within 48 hours once the thermometer passes 40 °C: green algae, a saturated filter, and a recovery that costs more than a month of maintenance. For rental villas it is worse: a green pool at check-in means a one-star review. The right time to act is before the water changes colour.

What our clients say
“The pump had been roaring for months: diagnosis on Tuesday, replacement on Thursday, silent filtration ever since.”
Nadia B. · Marrakech“We called them for green water treatment, then called them back for the winterizing and the heat pump. Nothing more to add.”
Karim E. · Marrakech“After the sandstorm the pool was brown: recovered in 48 hours, without draining. I thought I would have to empty it completely.”

500–900 DH for a pool up to 50 m³, 900–1,500 DH beyond, products and vacuuming included. After the recovery, we propose a maintenance plan so it never happens again.
Three causes that combine in Marrakech: filtration too short (12–14 h/day are needed in summer), chlorine destroyed by UV for lack of stabiliser, and 28–30 °C water that accelerates everything. A weekly maintenance contract fixes all three.
Yes, but not with chlorine alone: black algae form protective cysts. It takes mechanical brushing, a specific algaecide and a prolonged treatment. We eradicate them in 2–3 visits.
Do not drain and do not throw in chlorine at random: stop swimming, keep the filtration running continuously and send us two photos on WhatsApp. We come with the right dosage — a badly dosed shock damages the liner and does not kill the algae.
