Bubble Algae

It's not cyno...I know cyno. I've asked many and not been able to figure this out. I have a fairly new tank (8-9 weeks old), so I know algae is a common problem. To make matters worse, I used a RO DI that had been outside for some time and had filters that needed changing and too had algae inside (dumb, I know, but somehow I rationalized that it would be ok since it was being filtered). First I had a hair algae which my tangs seemed to take care of. After a couple of weeks I put in 250 crabs and 100 snails just as another type of algae was appearing to replace the hair algae. This algae covers everything including the snail shells and accumulates bubbles of air on the surface. Lots and lots of bubbles. The snails and hermits seem to be eating it, but they can't come close to keeping up. I have cleaned the corners of the tank, stirred the substrate and cleaned the back wall entirely and the algae and bubbles will be back within 24 hours. It's been like this for a several weeks now and I keep thinking it's going to disipate, but it hasn't. Overnight a film of powdery type algae covers the glass. It appears to just blend into the water when I use my glass cleaner on it. Do you have any ideas? Is it just because it's still a new tank and will work itself out? Do I need more critters to battle it? Do I need to start making water changes with new RO DI water? Does anyone know? Thanks for your help.
 
Whatever you have, I really dont' think it's bubble algae. Google bubble algae. There are several good sites I looked at when I was trying to ID mine.

How long do you run your lights? Cutting down on the light time may help. If you have FO, I'd turn them off for several days.
 
Yeah....I'm gonna try cutting the lights off for a day and see what that does. I know it's not "buble algae". I saw a pic of it and mine is tiny air bubbles forming on top of the algae and the air bubbles are not coming from my sump. I have two blue actinic and 2 metal halides. thanks.
