Do you take the gravel out, rinse it, and put it back in? I noticed when I put my gravel back in after washing it, air would get trapped underneath it. It would then slowly release and make bubbles at the top. This only lasted about a day though. If it is longer than that and you still see bubbles, your Betta could just be happily building a bubble nest. Do you have pictures? It would help to see what you're talking about.
