Do not panic. They are just air bubbles. If they are along the sides of your tank--you have two choices.
1) leave them there and they will go away over time
2) rub your hand along them to "wipe" them off
If they are in the middle of the tank, is the force of the water being pushed back into the tank producing them?
I am not familiar with the Top Fin 10 power filter--how much current does it produce underwater? How high is the water level in the tank? Is it up to the return of the filter?
