Rainbow Lifegard fludized bed filters

Due to its unique shape, the Lifegard Fluidized Bed Filter is an extremely efficient...high capacity �biological� filter. Aquatic organisms excrete toxic ammonia as a metabolic waste product...with additional ammonia produced as food and other organic matter breaks down and decomposes. This toxic ammonia (NH3) is converted to another toxic compound nitrite (NO2) by the Nitrosomonas species of bacteria. The nitrite is then converted to a relatively non toxic compound called nitrate (NO3) by the Nitrobacter species of bacteria. This process is known as �nitrification�. A �biological� filter is a vessel where nitrification occurs and soluble waste is removed. 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 Rainbow�s 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.
