In my opinion, 20 watt's of NO lighting won't be enough to see any significant growth from the caulerpa. The more lighting the better.

I'm running 96W's over my 30G refugium. ;)
I agree. I got two 250 W MH for my refugium (a 125 g tank)
I put my frags there, Macro algae and also use it to get my finicky fish to eat and get use to captivity food and fatten them up befor release them to the main tank.
