From what I have heard the actinic supplemental is more for us people. It is also really nice if you want to do a dawn dusk cycle. For instance I intend to put either 14k or even 20k mh on my 120 (planning) --I think the blue really looks good is why--but I will still most likely have a supplemental t5 bar because I really like the dusk/dawn, plus I can put in purple too if I want and have the colors pop. Plus I think it may give the corals a chance to get used to there being a light on instead of flick instant sun overhead. That could just be my adding a human element to it, though , lol

so many choices...
I have a question though based on what I've just read...
Is it really that beneficial to add actinic lighting to a 14k MH setup or is it a choice that is more based on the appearance?
