How is algae growth limited without the use of chemicals?

Since natural swimming pools use the same biological processes of filtration and sanitation as lakes and streams, there is a theoretical risk of harmful algae blooms as seen above. These algae blooms have been known to close beaches, and are generally a result of excess phytoplankton growth. Blue-Green algae (Cyanobacteria) is the most common phytoplankton … Read more
