Some kind of Algae I think. ID Help?

[Glasswalker]

Hey, so this started growing a few days ago on one rock only in my tank. This rock was a live rock from a friends tank, the remaining rocks were all dry Marco rock.

Tank is now cycled, and doing well, but this one rock started a couple days ago growing this tan/clear "fuzz" and I'm not sure what it is...

First off looking for an ID, secondly what eats it, so I can guide my next couple livestock purchases accordingly

And in addition, any further info on what might be feeding it and so on would be great!

Here is a pic of the stuff itself. It's tan/clear and covers most of the rock. You can see it blow/move in the current, medium current in this area. It's about 3-4mm thick on the rock:


And here is one of 2 rocks side by side. The clean rock is what the rest of my tank is like, just this one rock affected. Hasn't spread at all.


My params right now are:
Salinity 1.024
Temp 78.5
Ammonia 0
Nitrite 0
Nitrate 0
Phosphate 0
ph 8.0

Thanks!

Yes definitely new tank. Only just finished cycle a couple weeks ago.

Old algae coming off I think.

Bryozoans is another possibility.

@saltyfilmfolks Oh, hadn't thought of that. That's totally a possibility.

@cloak thanks! will look that up!
