One 65w pc over refugium or two 65w pc's?

I have 2 65w pc's laying around that I'm going to put on my refugium. Both bubls are 50/50. I'm assuming more light means faster growth from macro which means less nutrients but will it really make a diffence if I only have one or two bulbs?

Tank is a 110g w/ about 30-35g sump/fuge.

Macro likes light but I don't think it even has to be sw lighting. If you have both why not try one for a month then if you think it's not growing fast enough, add the other.

Do you really need that much light over a refugium? I've only got a 12" 10,000K bulb over mine...

I would say one 65w would be more than enough. JMHO.

I guess the actinic part of the bulb really does nothing for the macro? So I"m guessing out of each 64w bulb I'm only getting 32w of usefull light?

Somebody told me they use their old pc lights after they replace them from their reef tank, would this be ok to do?

From what I hear, macro is pretty easy going about light. I've heard of people rotating their PCs down to the fuge with success.
