Name that thang!

since my tank cycled I've been seeing more and more of these little white dots on the rock. They are about 1/2 to 3/4 the size of a paper punch out. What are these things?

[Reef_Angel]

Did you take the photo from the top down? Get some angle shots. To me it looks like a build up of kalk.

[BUGZME]

I agree.

[pro2k]

kalkwasser? I haven't been using any supplements at all yet. Doing a little research, someone has seen something like what I've described and someone suggested it was barnacles. ????

Barnicles look a bit more like tiny volcanoes, but a possibility for sure...

[JustDavidP]

Too perfectly round to be a barnicle. Plus...most barnicles that make it into our systems die within months. Unless you've got a real nutrient rich tank. If you have them, you'll see the little filter fans pulsing from the slit in the calcerous shell. They move quite fast.

I think someone's dropping bayer asperine in your tank ;) Just kidding. Let us know if you find out more about them. For now...they are UFO's Underwater Foreign Object.

[Reptoreef]

Almost resembles a vermitted snail with a white door.

[JustDavidP]

Yeah....butttttt........

There is no defined calcerous tube? Not that I can see in the picture.

Pro2K. Do you ever notice mucous strands, or weblike substance coming from the white dots?

[pro2k]

nope, nothing coming out of them. And they don't appear to move. They just showed up overnight! Maybe they are little UFO"S!!!! There seems to be less of them today. They are circular and concave in the center. And about the thickness of 2 credit cards maybe a bit less. I can't seem to get a good picture of them but here is another:

Eggs of some kind, maybe????
