Understood.....I was just merely pointing out that I have seen a few that have had success with leds and I think there's just not enough information to disprove them at this point. I think there are to many variable between the tanks, that make it hard to somewhat pinpoint what is actually going on. You could make the same claim as to 2 individuals using the same MH bulb ballast combination, and 1 suffers poor results, and the other has great results....To many variables IMO.
