Vertex omega 130

So I got this skimmer a couple of days ago and got called out to work before I was able to get through the 24 hour break in. now my girlfriend says it's still overflowing. from what she's sent me and what Iv read there are bubbles below the bubble plate, this means there is something in my water? My first step when I go home is to replace my carbon. Am I on the right trac or should I be looking in a different direction?
