ID macro algea please.

[Myanth]

I am having trouble getting a picture uploaded so this may be pointless but I'll ask anyways and keep working on the picture.

I have an issue with purple macro algea. This stuff grows in pads almost like a potscrubber or SOS pad. Very coarse and stringy, deep purple with very small bubbles on the strands. It does not grow very rapidly and never grows out in strings, always in pads with no colour variation towards the root. Although it is a great media for pods and little bugs to breed, I am starting to have issue with it shading some of my slower growing corals so I need to remove some. I haven't as yet found anything that will eat it, so manual harvest has been my only recourse although it will re-cover any area that I have removed it from quite quickly. If anyone knows a natural inhabitant that may feast on it, I would love to know.

Thanks.
Mike
