I noticed when my water level is low in my tank then more bubbles are forced into the water. Since I have a planted tank and have learned (on this forum) that water surface disturbance is, in short, not ideal for planted tanks, I keep my tank filled as high as possible to minimize the surface disturbance. This also reduces the amount of bubbles in the water. I don't think the bubbles hurt, though. I believe it oxygenates the water (someone correct me if I'm wrong?).
Does it look like the bubbles are coming from the filter?
