I have 96w of PC over my 30gal refugium. That is probably on the higher end of the scale when compared to other people. You can also use a simple grow light if you are just planning on growing macroalgae. WHat size refugium were you planning on using?
I am experimenting with a 500 watt halogen bulb. I must say the macro growth is outstanding. I am trimming at least once every 4-6 days. Fauna growth is not stunted. One problem, macro is not the only algae growing, I have spots of 3 different nuisance algaes. They have not transferred to the main tank, seems it needs that light to survive.
Well i have the sho n gro light from home depot 33watt is been good. I have a question about macro algae my refugium is really shallow like 6 inches of actual water and about 2.5 of sand, what is the optimal species of macro algae to grow, i have some long bladed calerpa i believe.

Optimally you should have at least three different species of algae, one of which is not Caulerpa sp. Any three will work but I would suggest a slow growing red, a fast growing green and some type of brillo or maidens hair algae.
Bang Guy- would 3 species fit in a 10 gallon with 2.5 in sand bed? I want to have grape calerpa and 2 others (following what you said) which would you reccommend like their street names so I can find them. Thanks
