Trying to figure out what's going on

[ArgonDreams]

I have been researching why my Zoanthids have closed up and string like "hair" have come off of the colony. I can't seem to find an exact match, some are close but not quite. So I figure I would take come pics and post them. First the water perms:

Ammonia: 0
Nitrite: 0
Nitrate: 0
Calcium 440
Alk 9.3
Phos: 0
Ph: 8.2
SG: 1.025
Mg: 1300

I perform Water changes weekly, I have good growth on all my corals, and in the picture to the left of this colony is a frag FROM this colony, it was split maybe 2 months ago, so it has the same flow, same conditions and hence why I am confused. Here are the pics:

The Colony that's closed, pic is kinda fuzzy, notice red hairlike structures at the back:



Picture of sister colony next door:



Another pic of the Colony and surrounding area:



There is a Trumpet coral near by but it wasn't there when this started so I discounted that out of hand, but I can move it. It did start when I saw these hair structures growing in the back. They are long and reddish and don't grow terribly fast. Any ideas? Move it down the rocks? Pull out the hairs? I own some seachem reef dip and was thinking of that.

Thanks for your help and ideas.

That is Wire Algae ( Gelidiopsis ) , it will not kill your polyps. It should grow very slowly. If it continues to grow and spread toward your polyps, it can over grow and prevent them from opening. They become more of an irritator then anything. You can remove it by hand. Herbivores love it and many Tangs will eat it as well.

Pics are too small. Sometimes zoo have diseases. Fungus or necrosis.. Look at your zoos carefully. If they have white spot, they are fungus. If they become transparent, they become rotten. If you can see some diseases, remove that part and dip the zoo.
