Or get in a wreck because you're the only person going 50 mph on a 75 
mph highway.

I don't think any sane person would chose fast-growing for the sake of 
having to trim plants and add nutrients all the time. I think the point 
is to supply enough light that the plants grow quickly enough to 
out-compete the algae. Some plants require more light than others ... 
that's just a fact. That's why the terrestrial world has shade plants 
and full-sun plants.

I still snicker at the idea of adding CO2 to water without dissolving 
it, but we won't go there.
