It is important to conduct a careful inspection and analysis of the body of water that will be treated for algae. Filamentous algae (also called pond scum, pond moss, string algae, hair algae, frog spittle or water net) begins growing on the bottom of ponds on surfaces like rocks and logs and resembles green fur. Filamentous Algae will often form mats that float on the surface of the pond resembling wet wool. Most people would recognize filamentous algae better by the simpler terms “pond moss” or “pond scum”. (10) Examples include filamentous algae such as Spirogyra, and waterweeds like the Canadian pondweed ( Elodea ).

Filamentous algae is the type of moss you see on some ponds that has long, intertwined threads or filaments. Excessive algae can cause oxygen depletion when it decomposes, as a result of natural die-off or an algaecide application. In the case of filamentous algae, single cells reproduce and join together into long hairlike strands or colonies that grow toward the water surface. Algae growth is sometimes referred to as a \"bloom\" because the algae grow so quickly. Filamentous algae can be raked or seined from the pond. Most pond owners commonly refer to this type of algae as \"pond scum\", but can often be called string algae, or floating algae.
