Strong actinic spectrum, dim lighting or very blue spectrum lights are nessecary.

I don't agree with that notion anymore, I am growing coraline like crazy with high PAR levels than a iwasaki 250 watt. even with my ABs that were out dooing some iwasaki 400 watt setups I still got good coraline growth. I just put the 14K bulbs back in the tank so now I will see if I get even more growth (which would support the theory a little)
I now belive that you might not get the same color of coraline but you will still get coraline if your main conditions are right. befor the move I have green, light purple, blue and pink coraline on the rocks but only pink and light purple on the glass. sence I totaly scraped out the tank when I moved I now have light purple starting on the glass again and the other colors going nuts on the rocks.
