It happens it will go away in a few months, It happened to my 8 then it went away!

does he have the water filled above the "minimum" line on the left side of the tank? Typically the water is too low and the pump begins to spit bubbles when there isn't enought water in the chamber.

super glue anywhere you think air may be getting into your tank. I had this problem several times, but it kept reoccurring and this has put a complete stop to it.
