I'm in need of a good Algea eater in my 40 g frag tank. I've tried the snails and hermies, ive got a lawnmower blenny. Would a small small yellow tang make quick work of the Algea it's mostly hair Algea. I've drove my mag up to 1400 I run gfo and skim heavy. Po4 is 0 it's only on the frag plugs I've got from everywhere and everyone.
