Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants Floating algae

Floating green specks in the water column are a species of algae that exists as a colony or clump of algae cells. Numerous algae species in a few groups of algae have this growth pattern. My best guess is this one is a specie of bluegreen algae also known to belong to the large group Cyanobacteria. Most all species of algae have a preference for a certain combination of water quality characteristics where they prefer to live and when conditions are best in terms of nutrient combination, they bloom. You have a bloom of some specie of algae.
