What is this?

For some reason the description did not post with the picture.

Anyway yesterday I came home to a find a couple of patches of white crusty looking material on some of my "new" live rock, then today there were several of these white oval egg shaped particles around the patches. Can anyone help me ID these patches / particles?

The "new" live rock (marshal island) has only been in the tank for about a month and is just starting to develop some pink, red and lime green coraline patches. The tank itself is only about 3 months old.

Thanks in advance - Dae

 

I will try. It's a corner tank (bowed front) and it seem like the closer I get to the glass the more distortion I get.

 

I tried several settings macro, zoom, macro zoom, auto-focus, manual focus all on a tripod and the best pictures were only marginally better than the one posted. The patch is toward the back of the tank and I cannot get the camera close enough to it to get a really good shot. That along with the curvature in the glass is giving me trouble. I think the only way I am going to be able to get a really good picture of it is to take it out of the tank and I don't want to do that.
