While the red algae, known as Noctiluca scintillans or sea sparkle, has no toxic effects, people are still advised to avoid swimming in areas with discoloured water because the algae, which can be high in ammonia, can cause skin irritation

 Algae are photosynthetic organisms found in the water requiring warmth, sunlight and nutrients to grow and reproduce.
