The green scum shown in this image is the algae bloom in Lake Erie. Within aquatic ecosystems, algae assumes a pivotal role by utilizing photosynthesis to transform water and carbon dioxide into sugar, concurrently releasing oxygen as a by-product. However, inadequate management can create significant environmental consequences.
Green water is an algae infestation that is suspended in aquarium water. It does not settle on surfaces. They are typically of the genera Chlorella, Ankistrodesmus, and Scenedesmus. It is a very common infestation to have in newly established aquaria, but may also occur after temperature swings or nutrient imbalances. [7] Once established ...
The fungus-like protist saprobes are specialized to absorb nutrients from nonliving organic matter, such as dead organisms or their wastes. For instance, many types of oomycetes grow on dead animals or algae. Marine saprobic protists have the essential function of returning inorganic nutrients to the water.
Krill feeding in a high phytoplankton concentration (slowed by a factor of 12). Filter feeders are aquatic animals that acquire nutrients by feeding on organic matters, food particles or smaller organisms (bacteria, microalgae and zooplanktons) suspended in water, typically by having the water pass over or through a specialized filtering organ that sieves out and/or traps solids.
In the wild, this algae grows in shallow water environments. It is calcified and its base is white due to the lack of Chlorophyll. In the aquarium, this algae will deteriorate if other algae is allowed to grow on its surface and should be exposed to fluorescent lighting for dense frond growth (though the algae can be grown under LED lighting).

An algae scrubber allows algae to grow, but the algae grow inside the filter instead of in the aquarium or pond. This removes excess nutrients (scrubs the water), diminishing nuisance algae in the aquarium or pond . Nuisance algae in the aquarium or pond are not to be confused with the desired algae in the algae scrubber filter itself.

Algae is most commonly caused by an excess of nutrients and waste, so aquarists will perform water changes to lower the nitrates present. [46] Another method is the use of animals that consume algae , such as some fish (notably cyprinids of the genera Crossocheilus and Gyrinocheilus , and catfish of the genera Ancistrus , Hypostomus , and ...
