I had stock actinic on my 12g nanocube and grew softies without a problem. I upgraded to leds and the colors are better but the corals grew just fine without them.
I have a biocube 14 and i just switched over to leds...I removed the lid and hung an AI nano, no complaints so far....but anyway my girlfriend has the biocube 29 and she is running the stock lighting and she is having some good growth on her hammers, green star polyps, and mushrooms...only thing that didnt do well was the trumpet not too sure why...You will have to watch for algae growth though because we would run them all (LED accent strip/white/actinic) for 12 hours a day and had to dial them down to 10 hrs
