Nearly every pond owner is forced to deal with algae control at some point and time. Typically algae is found in one of three common forms:

Filamentous algae is made of long strands of algae cells joined end to end. Often referred to as “string algae.”

Chara is a bottom growing “branched” algae that is often mistaken for other aquatic weeds. A strong, musky odor and gritty texture are hallmarks.

Planktonic algae or “pea soup algae” is caused by microscopic algae cells free floating in the water.
