Blue Algae

• Blue algae, commonly known as blue-green algae, are made up of cyanobacteria. This algae is happiest growing in nitrogen and phosphorous-rich areas.
  
  

Features

Geography

Considerations

• Algae in aquariums and fish ponds forms an important part of the marine environment, both as food sources and oxygen producers. But some blue-green algae contains toxins, and can cause problems as part of the food chain.
  
  

Fun Fact

• Both blue and green algae are commonly used as dietary supplements. The two most common supplemental algae products are Spirulina and Aphanizomen flow-aquae.
