Help with coralline algae identification. Pink, white, red?

[Dxpert]

Is all of this coralline algae? I assume the pink is, but I'm not sure about the white or red.

White? http://i1050.photobucket.com/albums...F-875B-4A5E-BE3E-4F00CA41215C_zpsvdvsnb5a.jpg

Red? http://i1050.photobucket.com/albums...4-7222-4D41-8789-9BC34D676E7D_zps7skzk0id.jpg

Also is this a small feather duster?http://i1050.photobucket.com/albums...9-5905-445B-94E1-2BC53C8FF280_zpsxvqsraap.jpg

So after doing some more reading it would seem that the white is probably bad, the coralline algae has died.

What about the red?

The white (picture #1) is dead coralline algae with either deep red coralline algae or cyanobacteria (it's cyanobacteria if it will rub off with a tooth brush) growing on the old dead coralline.
In picture #2 I see pink coralline and either again deep red coralline or cyanobacteria.
#3 does appear to be a feather duster.

yes coralline algae.. its not a problem..

thats a tube worm/feather of some sort..
I've got tons.. my sump is full of ones with white tubes/red feathers..

welcome to a new tank.. the new found life/creatures/sponges on "live rock" is the best part IMO..
very little if any actually causes a problem or is of any concern..

some stuff here and a few other places to help ID it for you..

Great info, Thanks mcgyvr and thegrun!

I did a little rub test with a toothbrush and it does rub off. So I'm suspecting that I do have a bit of Cyano. I guess back to the forums to do some reading on how I can get rid of it.

Oh the joys of a new tank!

cyano feels like slime bacteria and will easily come off with just a light finger swipe..
It could just be "flaking" off dead/weak coraline... it sure doesn't look like cyano to me from that red picture
