What is Green Algae?
Green algae is the most common form of swimming pool algae, typically appearing as a slimy green film on your pool’s walls, steps, and floor, or as a cloudy green tint suspended in the water. It is a microscopic plant-like organism that thrives in warm water, sunlight, and the presence of nitrates or phosphates—often taking hold when sanitizer levels drop, or circulation is poor. While unsightly, it is a very manageable issue. It essentially feeds on the organic debris in your water, turning your pool into a “swamp,” but with the proper chemical treatment and physical removal, it can be eradicated quickly.
