notice that ocreefmaster is not using any white bulbs, you really dont need the white bulbs when your running ati blue +. they have higher par then most white bulbs anyways. i gave my tank 2 white bulbs and only 2 blue+ a purple and a actinic, and im about to pull the actinic and put in another blue. i would say they next time i do a complete bulb change i may even ditch one of the white bulbs too and get another purple. right now it has an icy white/bluish look, i would think ocreefmasters tank has a much stronger blue look without any white. its what ever your looking for as far as appperance.
