I am asking about th red bubbly stuff

is it good or bad

now located in mantis area of my reefugium

thank you
 
Looks like it could be a variant growth form of some botryocladia, but its hard to distinguish from those pics. Could you try blowing the sand off and getting a clearer pic?
 
Iammatt219,

I have what looks to be the exact same stuff. I'm no longer convinced that it is actually Botryocladia but if it isn't, it's a close relative. I have a couple algae books that list about 5 genera that look pretty much just like that. Those dark red / orange spots are reproductive structures and I think you have to look at how those are put together to ID it even to Genus. Anyhow, it isn't "bad." It grows slowly and is easily manually removed. I imagine most sea urchins would love to eat it, too.

Kevin
