Beneficial bacteria attach to the media within the Lifegard Fluidized Bed Filter creating a thin film around the sand grains. Water is pumped up through the unit lifting the sand into a fluidized bed. The beneficial bacteria attached to the media draw in dissolved wastes (ammonia and nitrite) oxygen, supplied by Rainbows exclusive water fall device and other required nutrients from the passing water converting them to relatively harmless nitrate.

The sand grains are in continual free fall through the water resulting in an excellent transfer capability between the liquid and the bacterial film on the media. The enormously high surface area combined with this excellent transfer capability creates the perfect habitat for bacterial growth.

In addition, the sand grains bump into each other frequently knocking off excess debris and providing a self cleaning function which allows new areas for bacterial growth.
