Clove polyps invading!

[JohnnyReeftank]

Hey guys....I noticed these maroon clove polyps spreading about 3-4 months ago and at first I didn't mind. They are pretty small and at first glance it just looks like coraline covering my rocks and they don't seem to sting anything, but they are definately starting to be an issue with my Zoas. I've tried scrubbing them off and they are back 2 days later....I just started running carbon and GFO again so I'll see how that works but besides that, are there any other suggestions out there on how to get rid of these suckers??? Sorry for the iphone pics

My Coral Beauty Loves them. I used to have LOTS, and they've been toasted. I think I got lucky, he hasn't touched anything else except for a dieing pocci.

Now that I think of it....it's been about 3-4 months since my Sixline wrasse went MIA.....maybe he was keeping them in check?

They are really hard to control and will eventually take over your zoas. A sixline wont eat them. The only thing that worked for me and I still have to control them, is too scrub the hell out of them with a really stiff brush. I found that the thickest brush I could find was a denture brush.

IME, this coral seems to pop up in my tank when I let my nitrates get out of control...

It seems to show up along with hair algae within my system when I've been neglecting water maintenance...

anyone else find this to be the case?

If so, should be your nitrates you're looking to control rather than the polyps.
