quick Q bout Bulb spectrums

[whackamole]

Its time for some new bulbs in my light. And i wasnt sure what the diffrnces between the blue and the white bulbs are. Do the bluer actinic bulbs have just as much effect on corals as the white 10000k bulbs. Or are the whiter bulbs more effect as far as coral growth goes.??
I would like to make my light more blue but i dont want to lose any spectrum.
Can someone help clear this up. thankyou

you 100% need white 1000k lights and actinics are optional. some corals grow better under actinics and some under white
