I fail to see that we are at odds. I have implied that carbon in the water
is the limiting factor in establishing a high macrophyte:algae ratio when
the four conditions above are satisfied. The evidence in your last paragraph
supports this idea. From your first paragraph it appears you may have taken
what I said about CO2's auxiliary effect on phosphorous to be a claim that
this was the most important effect. I intended to say exactly the opposite.
