Not a simple matter
Cyanobacteria is natural. It can be more or less prevalent depending upon weather and water conditions in any given year.
Treating chemicals are all toxic and people cannot use them in public waters ever.
Treating chemically may knock down a Cyanobacteria bloom...however may also kill off natural algae which then leave more room for Cyanobacteria to grow.
Poisoning Cyanobacteria may cause cells to rupture and thereby may release Cyanobacteria toxins.
Falling and decomposing blooms may reduce oxygen and cause fish summerkill.
Poison can also kill fish and/or the food fish eat.
Cyanobacteria is not always toxic however most don’t have access to testing to know for sure.
