I forgot to mentio water movement. As Olga and Carlos indicate, water
current is likely to be another important variant. Maybe because the moving
water keeps the algae in fresh supply of nutrients and CO2... especially
when some nutrients (including carbon) are in short supply. In my one tank
that periodically gets BBA, the outflow of the submerged filter spray bar
is the first place I see it. In nature, BBA is found in fast flowing
streams. That is also why it is equipted to attach so tenaciously to objects.
