Pool water turning green — Dordrecht, South Holland
Green pool water is caused by algae growth, typically from insufficient chlorine levels, poor filtration, or unbalanced pH. While mild cases can be treated with shock treatment and brushing, severe algae blooms may require professional intervention including draining, acid washing, and chemical rebalancing. A pool technician can restore water clarity and set up a maintenance plan.
