I'm sure it won't be the last time we see this statement.

I'm curious why plants do so well with additional nutrients in lakes 
with lighting levels multiple times higher than we have in our brightest 
tanks. It seems that the conventional wisdom has been teaching us that 
plants are mainly CO2-limited, and that low levels of CO2 will assist 
algae outbreaks, but these findings seem to indicate otherwise.
