I have some sort of algae growing and and I would like to be able to identify it and know how to get rid of it. It is very stiff and it is very hard to pull off the rocks. Any help would be appreciated.

Take whatever its on and take it out.    This stuff spreads fast and soon it will be throughout your tank.  The only way to get rid of it is to dose your tank with Kents TechM magnesium. You have to raise your mag to 1700 and keep it there for a few weeks before it will die.  It took me 2 and a half gallons before it started dieing.  And it has to be Kents Tech M.  Dont ask me why, but its true.

That's not Bryopsis and high Mg won't do a thing with it.
It's common name is Sea Brush. It's related to Valonia. At one time, before I knew about it, I had a lot of it. The herbivores kept it mowed short. Smile It has such a strong attachment that when a piece can be pulled off, rock comes with it.

See this recent thread for info about what to do about it. http://www.utahreefs.com/forum/forum_posts.asp?TID=44482

You sure its sea brush?

I don't know a lot about plants, but it certainly does look like this brypropsis. I couldn't find any good pictures of Sea Brush though

I added 30 astria snails and a yellow tang about two weeks ago. I think its too long for the snails to eat however the tang eats it continuously.  I have cut feeding in half. Once a day half as much.
My tank is a 34 gal RSM. I have a question though, everywhere I have read about valonia algae says its a bubble algae however I see no bubbles. What am I missing?
 
Thanks,
John

Let me start out by saying that I am not an "algae expert".
Mark are you thinking of Cladophora?  If so then it is somewhat related to Valonia in the fact that they both belong to the same order (although this is a very distant relationship when it comes to algae).
 
Maybe you are thinking of Valoniopsis?  This is closely related to Valonia although I don't think it is ever called "Sea Brush".
 
I don't think I know what it is (I tend to think it is not Bryopsis since it usually has feather shaped tips, although there are like 40 species of Bryopsis).  Whatever it is I would try to keep a high alkalinity, feed less if you are a heavy feeder, replace your bulbs if they are old and remove it by hand if possible.  Most likely you won't have a problem.
 
Good luck.

Jake, you are more expert than me. I'm just a hick farmer. Smile I'd say that neither of those are what we are looking at.

If you look closely at the structure, you will see that it has a very strong outer shell with water inside. It's just a different shape.
I used to cut it short with my fragging scissors and the herbivores came after me. Unfortunately I never could get rid of it. Ouch
It's not a common algae so it's common name probably doesn't matter.
Here is possibly a red variety of the same stuff or at least a similar tough algae.

OK , I'm no expert on algea either, but I have been battleing bryopsis for 2 years now and I've tried snails, crabs, urchins  and none have worked.  The bryopsis I had also had the little feathers as Jake described, but also looked just like the picture above .  Just take my word, if it starts spreading everywhere you'll be sorry.
And even if Mark doesn't believe it, TechM finally worked for me.

Here are a couple more pictures. The strands are about 3/8 long. Not good pics but maybe it can help a little.

Mark,
 
The red variety above is possibly a large variety of Polysiphonia (I wish we had an algae ID expert on the board).
jmw,
 
I think you have Cladophora (although again I am not positive) and not Bryopsis.  I don't think you can usually see the cell wall segments like you can above with Bryopsis.
 
Another great way to get rid of these types of algaes is urchins.  I like the diadema genus since they tend to chew less on the calcareous algae.  Try and get little tiny guys so they can get in the tight spaces.

Sorry Brad, I was a little irritable last night when I answered that. I didn't mean that Tech M doesn't work on Bryopsis, cause it does. I meant that I don't think it will work on jmw's algae. But who knows. It's easy to try, so why not.Smile
Honestly, that algae looks exactly like the stuff I once had; strong bushy tufts of prickly fibers. That was so long ago, though... I could be wrong.

I agree with Jake that Urchins are a good bet.Thumbs Up

No problem Mark, that's why we are all here.  To give advice and different opinions. Nothing in this hobby is cut & dry.  All is good.

     I actually agree with Mark, it is not Bryopsis.  the common name is Maidens Hair.  It kind of has a texture of a bristle on a toothbrush if I'm not mistaken.  Tech M will not work on this Algae.
 
Sorry Brad Smile

I'll tell you what WILL work. Take the rock out and apply some hydrogen peroxide to the algae, after about 3 min rinse it off with some RO and put it back in your tank. Goodbye algae.

I have read alot about hydrogen peroxide. Some say just apply directly with a syringe, no harm to coral or fish. Also, I have read about Seachem Excel. Anyone have any experience with this?
I'm really leaning toward the hydrogen peroxide just wondering if I need to remove the rock or apply directly in the tank?  
 
Aquatica,
 I looked up Maidens hair, of all the algae pics I've seen that looks exactly like what I have. My only question is why is my yellow tang eating it like crazy?
 
Chlorodesmis is a green filamentous algae whose appearance is similar to thin blades of grass or tufts of hair. Its common names include Maiden's Hair Plant and Turtle Grass. It contains a toxic substance which deters herbivorous fish from eating it. It is a beautiful bright green plant that will bring a diversity of color and form to your marine refugium.
