Every once in a while I run across something I've never had or seen in my years of reefing. I've developed this red algae on my rock and I'm not sure what I'm dealing with. It does not blow off and will not brush off with toothbrush. I've been through several Algae Id pictures and closest thing I can find is Cotton Candy algae, however I have no puffy tufts anywhere. I have several Mexican turbo snails and a Urchin in QT for a few more days. Whatever this is seems to have no affect on coral and everything is thriving. Thoughts anyone??? Thanks in advance.
