Freshwater aquarium algae

There are many types of algae that are commonly found in a freshwater aquarium setting. They are typically considered a nuisance and subject to removal through the use of algicides, the release of algae eaters, and implementation of algae scrubbers. However, total elimination of algae is considered unlikely in a hobby aquarium. Algae can be used as an bioindicator to inform an aquarist on water chemistry and other conditions.
