aqua spider webs?

[bdbsean]

Help! I have some sort of thin web-like stuff that killed my coral and is attacking my anemone. It has a brownish tint and is all over my live rock.

Post a pic.

sounds like cyano or more likely dino's although the algae likely isnt the direct cause of the corals death but anohter sign that there ir some kind of other problem with your tank

Could it be the mucous from vermetid snails?

[Ludwigia73]

I think Zucker's got it... beat me to it. Vermetid snails release a thin mucousy spider web that traps detritus and food. If you follow it back to its source, there should be a little brown lump or a coiled tube that looks like a tiny coiled snake, with 2 little feelers sticking out, tending the webs. They're neat, I leave em alone, until they start irritating corals. I had one once where the tube was a tiny bit over 1/4" diameter, and stuck off the rock about an inch. That's a huge one. Most are about 1/4" long with 1/8 tube.

Sounds like dinoflagelettes...

What is the best way to remove that stuff? What is off in the tank for that to show up?

[Canadian]

Without a pic, I agree, it sounds like dinoflagellates from the description.

dino's are pretty hard to get rid of. Siphon out your substrate, siphon out as much of the dino's as you can. There is even one kind that attacks fish aka marine velvet. Lost a few fish to that and it took me awhile to figure out what was going on cause the spots look similar to ich but irregular because dino's are a single celled organism and reproduce by spreading like a mat and form clusters.

I had to siphon my tank out a few times, let it run fishless for a few months and now they are finally gone. It hitch hiked in on some frags from a guy in IL.
