Well Mark, it's only a name , but that Seascope article is the only reference to this fluffy red algae being A. taxiformis.  Do a Google of Asparagopsis taxiformis and go to the *.edu sites.  Where's Adam when we need him?

Like I said, nothing in my tank would eat it.  Luckily it's stayed in the sump and it's almost all gone now.  I've pulled it out, cranked up the skimmer and switched from xenia to macros in my refugia.

I've had that red cotton candy too... I don't think it's Asparagopsis taxiformis though.  Here are a few pictures of A. taxiformis:

A. taxiformis is a macro algae with distinct stalk and leaves, while the stuff pictured above is more like cotton candy without any real underlying structure.

Either way, it's a difficult algae to get rid of.  I don't think anything will eat it, you just need to reduce nutrients to the point that it dies off.  But if you do find something that eats it let us know.
