Stephanodiscus bineranus thrives in phosphorous rich and silica depleted waters. It reached peak abundance in Lake Michigan and Lake Ontario in the 1950s and 1960s, but since efforts to improve water quality began in the 1970s and grazing from the Dreissena sp. invasion increased in the 1980s, there have been marked declines in S. binderanus populations.

In a more recent survey conducted in 2001, Stephanodiscus bineranus was not found Lakes Superior, Michigan, or Huron. However, S. binderanus was present in Lake Ontario and had a few very large populations in Lake Erie reaching biovolumes of 32,028 ug/mL. This might suggest competition with other species in Lake Ontario and Erie.

The introduction and establishment of Stephanodiscus bineranus, along with Actinocyclus normanii f. subsalsa, were accompanied by the reduction of five native diatoms (S. transilvanicus, Cyclotella comta, C. michiganiana, C. ocellanta, and C. stelligera) in Lake Ontario.
