That's an interesting question, and we don't have strong data on the answer. GFO might be faster in binding phosphate than the algae are in taking it up, by which I mean the velocities of adsorption-absorption might quite different, leading to a relative starvation of one path. Since there are thousands of algae species, it's difficult to come up with a convincing test, but I've been successful with GFO when trying to discourage photosynthetic pests. GFO often seems to kill Chaetomorpha, for example.
