i have a 90g reef tank with 2 clowns, flame hawl, cleaner wasse, and a bicolour angel. i have torch coral star polyps yellow leather coral, and a pink tip anemone. i also have a varied CUC. for filtration i have a tunze 9005 skimmer and 110 lbs live rock. my problem is as follows. when i turned my lights on(3:30pm) i notioced this sringy white stuff that is consuming my whole tank. i mnean this stuff is everywere on every rock and coral. can anyone id this gunk i have had it once before and i thought maybe it would go away because it was getting sucked into my powerheads and broken up. it also flows in the current. my tank is only about 4 months old and i recewntly had a missing small pulsing zena that died and let go of the rock. it i s nowhere to be found. i also had a fish eaten by my Nem. a month ago.
if i missed any stocking its in my Signature. here are sopme pics of whats this gunk looks like.

Looks like a spider web...did you try to physically take it out?

 

[CoraLife]

no because all of it has been sucked into the powerheads and have broken down to invisible size.

have you tested your water?

Looks like the snot a ticked off snail leaves. It goes away after a while.

Have any snails?

 

[Horchata]

sea hair?

My corals make that when they are very disturbed. But it usually attaches to bubbles.

Saw that in my spare tank when I had the jet off for 3 days. It went away when circulation resumed. Didn't seem harmful.

Like your rock scape, especially the view of 1st pic. The pieces seem to fuse together so naturally.

those look like the feeding webs of a certain type of filter feeder snail called vermetids. they are sessile and look like the small calcerous tube of a feather duster worm of sorts, minus the plume. basically, the snail is attached to the rock, and from a very small (usually about 1/4 inch) tube it emits a cobweb-like thing that is sticky. it catches food, and the snail draws it in and eats all the stuff it catches. i always notice them when i mess around in the tank because all the dust gets stirred up and sticks to the webs. to be sure i'd follow the webs down to the rock, and i bet each is coming out of a small tube. here's a great article about them...

they are harmless, so you don't need to be worried if in fact that's what you have in your tank. like i said, i have a lot of them, and they are really of no consequence. hope this helps.
