What is it???

[trkdoc]

We have our tank up and running (72 gallon bow front) we moved last weekend....This is in a tank that has been up and running for over a year. We just bought it last weekend. It has some stuff growing that we have never seen before. They look like brownish red pollups of some sort and there are blackish beads in them (shaped like pearls) some are the size of b-b's and go up to a small marble. They are in clumps on the rocks and there are a lot of them. Are they good or bad????
Another thing growing is a bright yellow "sponge" looking stuff. It is on the under side of the rocks....again is it good or bad.
The rocks are covered with lost of purple algea and for the most part it all looks healthy.....
We just don't know what these things are....
Please advise

I thought bubble algae was geeen!!! If it is bubbles..don't pop them but remove them whole. When popped they create more bubble algae!
