Air Bubbles

[akopley]

Every 10 minutes or so...air bubbles come out of my sea swirls...is this bad?

imo no. i'm guessing its just like a whole group of microbubbles? I dont think its bad...doesnt do anything to the tank. the only thing i'd be worried (not even really worried) about is the pump having air in it...but mine do this also and everythings still working :) I think they get the bubbles from my skimmer...its just a hob (no sump) and it puts out a few bubbles, and my fluval intake is right under the skimmer return...so every day it shoots out a group of bubbles
