Here is what I've been dealing with:
The bubbles seem to form during the evening hours.
I know this is a bad pic. The dino/cyano/algae/??? is stringy with bubbles attached. The bubbles are at the end of the strings.
I had a lot of it hanging down from my frag rack. One member said it looked like dino, so I have been preparing for the worst. I replaced the frag rack. I just through out the old one instead of cleaning it. I then blew off the sps coral with a turkey baster. I didn't think about suctioning it. I also scrubbed some of the rocks with a toothbrush. This may have made things worse, since it probably spread it. I have the all the power heads on and will change out the filter media every day. I also started dosing 1ml of peroxide and blacked out the tank.
