personal opinion, running blues, or blue led's do nothing for our tanks, they also do not count as lighting, many people say I have 3 white and 3 blues,.........then you have 3 whites and 3 decoration lights, when the sun goes down on the worlds oceans, the moon light does not help corals or fish, feel better just one of my pet peavies when you ask people what kind of lighting they have, if blue/moon/pretty led's mattered then corals would polyp under"moon" lights or at night but they don't until the sun comes up and penetrates the oceans depths. If you have 6 forty watt bulbs, 3 whites and 3 blues, then you have 3 good lights and 3 decorator lights. I feel better now
The statement that blue does nothing would be totally in conflict with what Mr_X believes because he is running one of his tank with total blue.personal opinion, running blues, or blue led's do nothing for our tanks, they also do not count as lighting, many people say I have 3 white and 3 blues,.........then you have 3 whites and 3 decoration lights, when the sun goes down on the worlds oceans, the moon light does not help corals or fish, feel better just one of my pet peavies when you ask people what kind of lighting they have, if blue/moon/pretty led's mattered then corals would polyp under"moon" lights or at night but they don't until the sun comes up and penetrates the oceans depths.
