Help. What is this stuff

[c-razybutterfly]

So yea, i have just set up my first saltwater tank, and have added the live rock but one piece is starting to get what looks like spider webs all over it and it is spreading to the other rocks. What is it?, is it bad. Will it go away?

Probably cyano... and yeah, it will go away.

Pictures would help... if it is white (like most spider webs) it is not cyanobacteria. What it is, I don't know, but I have it on some of my live rocks, too....

I've noticed the same thing in my tank....someone told me it was snail-related....
