Tube worms??

[CKANE722]

So a couple weeks ago I thought I had snail eggs on the bottom side of one of my live rocks. Originally they were black and round in color like eggs, now they've turned purple, solid, and have little tubes growing off of them. Can anyone help me with what these are?

I also have this white, almost transparent mass growing on the live rock below it. Upper middle. Any help would be appreciated.

The transparent mass could be a sponge or tunicate.
