NOOB question

Ok so I should know this answer by now but i would like some input.. I built a 38 cree LED system, at full power some of my corals close up especially my bubble coral. yet at 75% blues and 40% white everything is open. I understand LED are a very focused light and seeing how i had these corals under PC's just over 2 months ago they may still be getting accustom to it. are my corals getting enough light with the blues at 70% and whites at 40% or am i starving them? basically what am asking is Does the Royal blue LED's feed my coral.. thanks!

 

Oh yeah the corals are getting enough light. Just make sure everything at the bottom is, if not you may need to lower some pieces and acc. them to the higher light levels. Blue is just fine, as far as color goes, to provide the corals with enough light.

 

also i didn't mention my kit is 20 RB's and 18 CW's all corals are 10 inches below surface and LED fixture is 6 inches above tank with 60 degree lens..
