Dinoflagellates or something else?

    Hi everyone!

    About a month ago I noticed this brownish stuff on the sand bed and then I noticed my bubble coral, hystrix, lepastria and other corals started to slowly die off. Then this hairy looking algae started to grow in my rock. It's mainly on the top of the rock in the better lit places. I think it's Dino but I'm not sure. I've done a three day blackout and nothing changed. I've been raising the ph (currently 8.4) and have dosed with peroxide and nothing has worked.

    Any ideas as to what this stuff is? Is it dino or something else and what can I do about it?

    I think it's something else. Dino looks kind of slimy and very often has little air bubbles trapped in it.

    Close up? And or Google and try to find a pic of it. Unfortunately one parameters is allowing these to grow but also hides it because it uses it so font rely on parameters

    It's hard for me to identify it. It doesn't look like any of the photos. It's brown in the tank and green if I pull it out and put it under normal light. It's not long and hairy, more light short, tangled bushes.
