Pool Water Turned Green — Madrid, Madrid
Green pool water is almost always caused by an algae bloom triggered by low chlorine, poor circulation, or a clogged filter. Left untreated, algae can stain surfaces, damage equipment, and make the pool unsafe for swimming. A pool technician tests the water chemistry, shock-treats the pool, brushes and vacuums algae deposits, and balances pH and sanitizer levels to restore clear water.
