Algae ID -- Dinos?

[Hype134]

I've been battling this algae for some time now and is actually beginning to kill some of my corals... brownish algae that has little air bubbles in it... i think its dinos but wanted to get others opinion. I've actually tried H2O2, lights out and no prevail... goes away temporary but always comes back... please help me identify...

I cant believe by your description that no one answered this question. Its excactly what dinos are so yes it is dinos. I would try the hydrogen peroxide dosing 1ml per 10 net gallons with a 72 hour black out. You will be shocked on the 3rd day how fast your corals bounce back. After your lights come back on do a water change and continue dosing for a few more days. It should be gone by the time your lights come back on. Also run carbon. Preferably in a hob so that the filter pad can catch some of the strings. I cleaned my carbon pad every morning

Yea... i actually did a 72 hr period and continued to dose H2O2 afterwards as well; however, still coming back... almost feel like i should try another 72 hours... i was changing GFO and GAC after a week, but im gonna try every other day... so we'll see if that helps, if not i'll try another 72 hours blackout.
