Strange brown algae/slime

[fearyaks]

Hey all, was wondering if you could help me figure out what this stuff is and what I can do about it. This is an sps tank otherwise I'd have thought maybe brown jelly.. Unless it can just live in the water without a host. All corals and fish seem fine. It's just kinda ugly.

Thanks in advance!

It looks kind of like Dinoflagellates to me.
