    I noticed today some things popped up on my live rock and I don't know what it is. I got it from a store that kept it in a huge tank with no fish or anything so I didn't think anything would be in it.

    I tried to get a picture but my water is so cloudy and the glass is dirty lol so it didn't work.

    The first type is small little grey things... they're attached to the rock and are made up of little spikes. Almost the size of a penny each and there are quite a few of them. I want to call them spores of something. The second thing is white and looks like a net... like a fish net you'd catch aquarium fish with. Then the third thing looks like a black or dark grey blob sitting on the rock. Does anyone know what these are? Are they harmful?

    I've been looking on google images but I haven't found anything that looks like these

    EDIT: Ok I finally got good pictures :D you'll have to look at them full size to see the texture of this stuff, even though it doesn't show the texture as well as I can see in real life. Click on them then zoom in on your browser

    A picture would help assess for sure. I do know that sometimes fresh (rather it's been in another tank or not) wood can grow slime on it. If that is what it is, it is not harmful and will go away in a week or two.

    On the other stuff, I am totally stumped (pardon the pun).

    If your water is cloudy, it could be that your having a bacterial bloom as well. Did you boil the wood or leave it setting in a bucket of conditioned water for at least 24-48 hours before putting it in the tank?

    Ugh. I just lost my mind. You're thread is started in the saltwater section. I'm not experienced in that realm. My apologies.

    Hopefully someone can help you soon.

    Hard to say for sure, given it's still a little cloudy.

    Looks perfectly harmless in these images, some of it is likely die off which is very common.

    Other bits could be the start of padina, a calcerous algae, not typically harmful though.

    If you can post some pics when it clears up, it'll be easier to identify, but generally, stuff that grows on the rock isn't too bad.
