At Griffith New South Wales Australia, Biosol has been shown to reduce incident P at the treatment plant by 75% when compared with Ferrous Chloride and Magnesium hydroxide dosing in the sewer catchment.  This P is forming an insoluble Calcium / phosphorus microfine sediment that is not available to the algae.  Dropping N or P will reduce the algae as Jose Martinez suggests.  Biosol treats the cause of the problem and not the symptom.
