I'm setting up a 125g mixed reef. Wondering if I can have anything in there which puts out a constant stream of small bubbles, such as a volcano. I'd like to have this mid to high in my rocks in the center of the tank. I've heard you can't have any bubbles at all in a reef, and I've also heard it's not a problem. Looking for opinions/experience on this. I know this is probably a noob question...but I am new at this especially on this scale and rather ask than be sorry later on. Thanks folks!
