Help identify this algae?

No offense taken.  No worries.  I have only been keeping salt and coral for 2 years and there are far more knowledgeable people than I.  But any of us can likely claim to know a lot about something and little about others.  I learned a lot about invasive macro alga and their eradication while dealing with a bryopsis outbreak of my own.   I developed a somewhat personal relationship with John Maloney at reefcleaners.org and he helped develop my knowledge.  He's a great resource and his prices on snails and clean up crews cannot be beat.  He is a good knowledge base and always willing to help.  I recognized your algae from my research and offered my assistance.  I think your course of action is right on track, and I bow to mark's knowledge.  He's a smart guy!  Get a bunch of those BIG turbos and they should munch it down well.  Maybe throw one of your tangs in the sump for a little while?  LOL  good luck!
