Pod?

Lights came on this morning and It looks like baby pods are covering all the glass, I dont remember seeing this 5 years ago when I was running a reef, my 2 Damsels are stripping them away, just thought it was really odd
 
yeah, its definately pods, they dart around alot, just never saw them like this before, plus this is a fairly new tank so I must be doing something right.
