Title: Lake that appears to be treated with Pepto-Bismol Written by: duddy on Feb 9, 2014 (https://biology-forums.com/gallery/47/4_09_02_14_1_46_15.jpeg) (https://biology-forums.com/index.php?action=gallery;sa=view;id=15214) This is Lake Hillier. While there are a few hypothesis, no one is 100% sure where it gets its pink hue. Comments: Lake Hillier is pink because Pink lakes tend to have a striking color due to the presence of algae that produces carotenoids, such as Dunaliella Salina, a type of halophile green micro-algae especially found in sea salt fields. Once the lake water reaches a salinity level greater than that of sea water, the temperature is high enough and adequate light conditions are provided, the alga begins to accumulate the red pigment beta carotene.
