didn't you read the part about not trying to be confrontational??? you might be the one who needs to lighten up... don't ya think? Anyway, sorry to the original poster for getting distracted from the point of the conversation... as you said originally, photosynthesis is much more efficient when there is a period of darkness. Doesn't mean the algae won't continue to grow, it just means that maybe it would grow faster if there was a dark period (and hence extract more nutrients in the process). However, i don't pretend to know everything, and this is just an opinion based on what I've read and learned so far (in grade 9 science class, right? )
