Myth or Fact?? Microbubbles??

Is this a Myth or a Fact??

Microbubbles can cause harm to fish by entering the fishes gills and not coming out.

Don't know about that one but when I kept fish in my sump with the micro-bubbles, most of them got Popeye.

I am in the myth camp. No hard data to support my position. I just do not believe fish are that fragile. I also cannot imagine with all of the potential turbulence/bubbles on a reef fish are impacted.

Thats what I'm thinking.....fish are in crest zones all the time and they have tons of bubbles.

While not really common it can happen. It is due to the water becoming super saturated with gases. It doesn't happen as often if tanks are left open and have lots of surface agitation to help promote gas exchange, but in a covered tank it can happen.

You really can't compare a natural reef to a closed system as the amount of surface area to allow gas exchange is way greater, not to mention that nobody is intentionally pumping air into the ocean.

I just watched Blue planet about reefs and there was a lot of bubbles as you said about the crest and was thinking the same thing
