| Lighting newbie stuff ....
#1 Actinics :
Specifically what do they do? I understand that corals benefit greatly from that type of light but I see TONS of different types of actinics... is ONE type better than another or is actinic actinic?
Do the actinics give off any appreciable light in the the visible spectrum?
#2 Daylight bulbs :
I see 10K and then 12K which one gives the most visible light (maybe brightest is more accurate)?
Which one would benefit a REEF tank more?
