What skimmer?

What changes have you recently made?

What did you do just before the bubbles came back?

 

its a seaclone 100. wife cleaned it up. other then that nothing.

 

Cleaning may have been the cause if she used something other than tank water.

 

she used a toothbrush and tap water

 

That may be it she removed the biofilm. It should stop once the film re-establishes itself.
