If you're using a 9002 then
A) that's way underpowered for your tank.
B) It does not have a surface skimmer so protiens (oils from food etc) will naturally rise to the tank surface and make some lasting bubbles unless you have surface agitation.

Ya it's kind of like an oil slick. No foam. Haven't had a problem until recently. Tank has been running fine for over a year now.
Nothing has changed in my tank. Maybe I hit the skimmer a little bit my last water change/media change.
