Been almost 3 years since this post was touched... but I have the exact same stuff that I have been trying to get rid of for 1+ year. I had a blue tuxedo urchin, but he would just eat around it. I heard a Naso Tang might do the trick but my tank is not big enough to support it (60g).

I have been putting 2-3 pieces of live rock in my sump and waiting about 4+ months for the stuff to disappear. However after switching cleared up pieces with stuff in display tank it eventually comes back.

Anyways any suggestions would be greatly appreciated. I have been peeling off what I can... but need to get rid of this stuff :(

I hate that stuff! It is a PITA to get rid of.

The faunamarin ultralith system gets rid of it. Took about 6 months with the basic 4 ingredients (rocks, bio and minS and bak), then a few more to really make sure its gone. I think I did a year total of "low nutrient" system (6mo ultralith, 6mo zeo) before I got bored with it. I still have some on one of my clams as it was moved to a different system recently and acquired it there. I just keep him away from the rock.

I have some also and don't mind it salaris blennie eats it and some angles eat it Naso tang I had ate it really well. It is some sort of macro algae at least the stuff I have after a while it started growing in bushy patches. it has a burgundy look to it and feels kind of like Velvet. My urchin does not eat it either but has picked a piece top wear looks like red Cheeto.
