I dont know if the photos made it to the post, just guessing on how to post them

I have this stingy, dense, branching stuff growing on my live rock, it is spreading fast and furious!!, Anybody know what it is and how I can stop it? I is a redish purple color

I can't really tell from the photos Wade but I am guessing Dictyota.

If it is, limiting nutrients will help, my Yellow Tang ate it up but a Rabbitfish might be better to try.

Here are a couple more pics, a little bigger, you can see it growing on the rocks on both sides of the open coral., it should give you a better idea of the size of it

only one that likes it is the brittle star, you can see one of its arms coming out of it[/img]

That is cyano under those polyps.

Wade, I think you have dictyota sp. algae. Not the easiest thing to get rid of. Most guys I have talked to about getting rid of this type of algae say to just keep harvesting it and eventually it won't come back. This approach has worked for me also.

I think I had (and used to have a lot more) of the same stuff. It is a dark red (burgany) and grows in thick patches. Some areas have thicker branches than others (in low flow area it seems). I have had to manually attack it only and it is slowly going away.

All I can say, is don't wait around for it to dissapear. Get rid of it manually as fast as you can. It will spread like a weed otherwise, mine did....
