[Naw! think surf line - lots of bubbles there! It just messes up the looks of the tank for a bit.
New skimmer? Then it will throw out bubbles for a couple or three days - relax, that's usual and typical...
Old skimmer and this just started? Hmmm, what changed? Change it back.
Depending on the skimmer, CPR bakpaks, for instance, have bubble boxes to catch the output to allow the bubbles to burst before the output enters the tank proper... yours may have that option as well.
Intank skimmer - someone else will have to speak to that...
Good luck!]
