Ah yes i forgot to ask if it was the long hair type or the short beard type. With the long hair algae (long like a woman's long hair (ok guys can have long hair too but you know what i mean!)) you just twirl it around the brush, very simple, very easy! If it's beard algae that method won't work, it's not long enough to get it wrapped around the brush.
American-flag fish are also said to eat beard/hair algae.
