To prevent the water in your swimming pool from being colonized by algae after the passage of bad weather loaded with sand from the Sahara, you must ensure proper maintenance of your pool. The water must be filtered and treated before and after, to best evacuate dust.
The turquoise blue water of your swimming pool could turn orange in the days to come. The sand from the Sahara should have returned to the Languedoc-Roussillon region from this Thursday, June 13, according to data from the prediction organization weather phenomena Predict.
Rains laden with sand dust from the Sahara”disrupt the water balance“, explains Alexandre Charron, manager of Piscines d’O in Montpellier. The main risk is that water “turns green” because of the mustard algae, a kind of yellow dust which lines the bottom of the pool and which is particularly difficult to eliminate. This germ, native to the Sahara desert, is carried by the winds and the rains. So, for the swimming pool owners, there are certain measures to apply to protect yourself from this risk. First of all, “flocculate your swimming pool“, that is to say applying a flocculating product in the water, which will have the effect of “collect fine particles into large dust” in order to evacuate them more easily.
You must then ensure that the pH of the water “stays at 7” (the recommended value in the region, due to the particularly hard water) and filter the water as much as possible. A false good idea, for the professional, would be to close the swimming pool: “When it rains, preventing water from entering your swimming pool is an aberration, you must use this natural and free water, it is the most economical and ecological way of filling!“Other advice given by the pool specialist:”You should not hesitate to go see your swimming pool specialist to ask for an analysis of the water in your swimming pool, it is often free.“
“Don’t hesitate to ask for an analysis of your swimming pool water.”

In general, Alexandre Charron would like to emphasize that you must always act preventively: put your swimming pool back into service as soon as possible, filter and apply chemicals in advance, before the situation requires calling a professional. “We usually tell customers that a swimming pool is like a dashboard with a succession of lights, green or red, and the goal is to turn off all the red lights as quickly as possible.“
Finally, for individuals who have the means to invest in the automation of their swimming pool, it is the most effective and economical solution in the eyes of the specialist. Water pollution by sand causes aesthetic disorder”but it doesn’t matter” summarizes Alexandre Charron: “if owners correctly use the chemicals appropriate for the maintenance of their swimming pool, there is no risk.”
