Jason I zipstrapped a piece of sponge (1/4 in thick, not too fine of mesh) to the bottom of the media basket (carbon in mine)........decreases flow ,increases the water level in "tower" therefore you can turn the air/flow down a bit....that gave me about 75% reduced bubbles....clean the sponge every week or so. To fix the rest I friction fitted another bit of foam on top of the basket just before the water returns to the tank.....hope this makes sense. If you can't figure it out mine is in the crawl space and is available for a great deal!!
....OR use the becket and sump...as guru Brad suggested.
FWIW....switching from PP to a Beckett is like upgrading from a Yugo to a Porsche.
