I was wondering the effect might be of giving corals only blue light, or mostly blue light?
Will they grow at all?
I was inspired to ponder this after looking at how pretty my corals look under my royal blue leds when the whites turn off.
Assuming these leds have more PAR than ever needed, will stuff still grow? Is PAR the only thing to consider when planning for corals? I could adjust the whites for 15% and the blues for 70% if that would be better.
My guess is that they would slowly begin to suffer from such a limited spectrum. Would they color up better?
Anyone have experience with this?I notice my LFS
has all their ultra colored stuff under blue light only when I look. (Acans, chalice, rare zoanthids, ect).
