algae growth

Green water problem

Algae growth is the proliferation of algae in water or on damp surfaces.

The phrase usually appears in contexts where such growth is unwanted—ponds turning green, aquariums clouding over, swimming pools becoming slimy: Excess nutrients in the lake caused rapid algae growth.

Factors like sunlight, warm temperatures, and nutrient runoff accelerate it.
