Most macro algaes don't need a lot of light,, compared to corals anyway,, something like a 36 or 55w PC is more than enough for a 10g fuge.
I don't know what your setup is, but if you can get the fuge at the same or higher level than the tank, (therefore feeding the tank by gravity), you will save lots of pods from getting munched by a return pump.
I highly recommend chaetomorpha algae for any fuge,, it grows like a weed and doesn't go sexual, doesn;t spread to the display tank,,, it's also pretty dense and seems to do a good job filtering particles.
