I've got this horrible looking brown gunk on a couple of my rocks. I tried doing some searching around and now my guess is dinoflagellates but I'm not 100%. In any case I need to keep this under control because it looks terrible and obviously I don't want it to take over.
If anyone can help me identify this and help me with a course of action I'd be very grateful.
