Aquarium Algae ID (updated) is a good place to look to try to identify an algae. I don't recognize yours from my experience.

It does look like you have more light than you need. You have 2.8 watts per gallon for about 7 hours, and lesser amounts for another 2 hours. The actinic and lunar lights are probably not significant. Why not cut one of the pairs of 96 watt lights down to only 2-4 hours? Then later, you could increase that time a bit if you wanted. Do you run the actinics just because you like the look?
