Coralline algae spreading?

[shawnn]

All these rocks shown were all white before and now they and starting to show all sorts of colors. Does this look like coralline algae to you guys?

It could be the start, but many things will grow on live rock. Whatever it is, it is good.

The rock on the left looks for sure to be growing some, don't worry though you'll be cursing the stuff soon enough! LOL

Thanks guys. Here's another pic of some rock and dead coral. I've been noticing big changes after I put in frags of coralline right in my overflow box, and dosing my tank with Ca @ 420 ppm

Thanks to a blenny I caught tidepulling, he ate up all diatoms and revealed what was hiding underneath.
