Why is it that one brand of VHO actinic has a purple/pink output whereas another is straight blue?
I assume that the purple/pink output is more advantageous for our corals?
Which brand(s) do you recommend?
I currently am using URI Super actinic R's and they have a very blue look to them, not the purple/pink I am accustomed to when I was using NO bulbs.
