It clears up after a while. My 10 is dirted and it took a while before the tank was clear. Mostly a bunch of water changes helped. Lots of dirt gets stuck on the mechanical filtration(sponges pads, w/e) in the beginning and cleaning those off helps get it clear faster.
I actually never really probed around in my tank to release the bubbles, but they did release themselves eventually and no harm was done to the fish or inverts I have in the tank.
