cob web looking secretion on acro

Anyone have any idea what this cob web looking crap is on one of my acros? sorry for the bad pic. if anyone has any info or insight i can try to get better pics, but if you're reading this thanks for taking your time. 

Mark thank you for your time,

I'm a little surprised that it had not disappeared overnight. If it is indeed a Vermitid Worm net then perhaps water flow across the coral is not strong enough to dislodge it. The net spreads out to catch food and then the worm pulls it back in to eat what was caught. Look for where the net comes together and, unless it has already cut the net loose, there you will find the worm. It lives in a hard tubular shell like a tunnel. It should be living on the rock near where the coral was placed or the rock to which the coral is attached.
In moving the coral from it's previous tank, the water now flows in a different direction causing the net to get caught on the coral. These worms are good filter feeders that help clean the water. Simply turning the coral 180 degrees may allow the worm to spread its net freely and to be retrieved without obstruction.

In looking at the pics, the aquascaping is great - artistic yet natural looking with good open water. I have a suggestion. Try moving the powerheads down the glass pointed at more of an upward angle toward the water surface. Also aim one of them so the stream moves really close to the new SPS. I assume it is the one on the top shelf.

Thinking more about it, actually I would try this:
Even better flow with more turbulence would be accomplished by moving one powerhead to the opposite side of the tank, down next to the sand with the stream aimed directly at the stream from the opposing powerhead. Have both streams meet where they hit the center water surface. This will give the maximum benefit of those two powerheads; water turbulance, wave action, excellent gas exchange and best possible pH. The powerhead pointing just past the new coral might be closer to one bottom corner. Try both lower corners for each powerhead and please let us know with a pic which placement worked best.

BTW, I don't see any evidence of pests on the coral. It is okay, and even desirable, to have a strong stream moving across it.

Aloha,

Hey Mark! 

Aloha,

After all my looking at the net, its threadlike appearance and such, I may be over-thinking it and Bryce may be right. It could just be sliming. (btw, Bryce, thanks for the frags. They are doing great. I'm ready for more. )

Ryan, I didn't realize that was you! Again, sorry the Sailfin didn't make it. So that tank is replaced by this one. I thought the background of this new tank was somehow familiar, in that two window corner. Congrats on being accepted into grad school. 
Is this Acro doing okay now?

Coincidentally, I have been thinking of you for the past week with regard to the subsurface coral greenhouse. Do I remember you telling me that you work at Cactus and Tropicals and that there had been a summer overheating problem? At which store are/were you working, Draper or SLC? Do you know of any other local greenhouses, maybe also private or wholesale greenhouses, that run year round? I visited C&T Salt Lake and spoke to an experienced gentleman, can't remember his name but he has long blonde hair. He answered some of my questions. (This week I'll be checking into J&J Nursery in Layton and Desert Gardens as were referred in the coral greenhouse thread). Thanks for all your help.

Mahalo,
Mark
