Very timely thread. I've been considering replacing some power compacts with NO because of the "harshness" of PC. The thing that has been stopping me is concern over downgrading the light. Now, I'm confused on how less intense lighting will make it easier to grow certain plants?tsunami said:Raul,
6x25w is fine for your 58g aquarium. Actually, you might even find it easier to grow some of those plants since the lighting won't be as intense as with the power compacts.
