I have the same setup on my 65g tank. I get gas bubbles all the time, but i haven't seen it affect my fish or plants in any negative way. The tank has been this way for over a year now. Like Monster Fish said, you could just use something to poke them all out. I don't even bother with it.
YES thanks you i just needed some reassurence and that did it the gas bubbles seem to be regressing and i fell safer noe thanks!
