what macro algae for a refugium?

[Deranged-Jester]

howdy all.
i was wondering what type of macro algae everyone considers as the best for refugiums? i read somewhere that calupra goes through a cell die off if not lit for 24 hours a day and that chaeto doesnt? any truth to that? also which one do you think soaks up more excess nutrient ?
