Identifying and removing algae in a swimming pool involves observing telltale signs and taking decisive action to restore clarity and sanitation. Algae typically appear as green, yellow, or black patches on pool surfaces, giving the water a cloudy or discolored appearance. To remove algae, begin by thoroughly brushing the affected areas of the pool walls and floor to loosen the growth. Next, test the pool water’s pH and chlorine levels, adjusting them to the proper range—ideally, a pH between 7.2 and 7.6 and a chlorine level of 1-3 ppm. Once balanced, apply a shock treatment using a high dose of chlorine to kill the algae, following product instructions for the correct quantity based on your pool size. After shocking, run the pool filter continuously to clear out dead algae particles, backwashing or cleaning the filter frequently to maintain its efficiency. Finally, consider adding an algaecide as a preventative measure and ensure regular cleaning and chemical balance to prevent future blooms.
