Pool water turned green after vacation? Dit is wie je moet bellen
Returning home to a pool full of green, murky water is one of the most common shock-and-treat scenarios. Algae blooms develop quickly when the pump is off or chlorine drops to zero for even a few days—warm temperatures accelerate the problem. The fix starts with brushing the walls and floor, then a triple- or quadruple-dose chlorine shock (bring free chlorine to 30 ppm for green, 40 ppm for dark green or black). Running the pump 24/7 while the chlorine works, backwashing or cleaning the filter frequently, and adding clarifier or flocculant to capture dead algae are all part of the recovery process. A pool technician can perform the shock treatment, test and rebalance pH, alkalinity, and CYA levels, and have the pool swim-ready in 2–4 days.
