If you don't like bubbles, put the filter intake at the bottom and output at the top and you get plenty of circulation. A spray bar on top will disturb the water adequately to get good air exchange, and the water of necessity will flow to the bottom to the output. You can also then plumb the filter so you can use that filter intake to drain the tank for water changes (siphoning a tank that deep is going to be a pain).
