Royal blue VS Actinic blue bulbs

[shimmy]

The tank is a 72gallon bow front, 48” long and 24” high. The lighting fixture is a 2 bulbs wide by 2 bulbs long that’s why I was thinking daylight in front and blue in the back but would it be more affective to have a 50/50 in the back for more daylight? As for corals I am not totally sure what I want to put into it currently all I get is one anemone and a Kenya tree. As for future corals im unsure I kind of buy cool looking stuff as I see it and just want to be ready for anything.
