I just added a few corals to my system last week and like an idiot I forgot to dip them. This week I noticed a few of these white/clear things on some of my frag plugs. Some are on acan plugs and some are on chalice. My corals don't seem to be stressing or receding, however I am. I took the corals out and brushed them with a tooth brush and these things came off. The bigger ones seem to grow longer. The smaller ones are circular. You can see them just under the coral between it and the frag plug. Any help would be greatly appreciated. Thanks in advance.

Can't see any thing, take them out and take a pic by them selves.
