RAINBOW LIFEGARD AQUARIUM FILTER
By PentAir Aquatics

FLUIDIZED BED FILTER

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.

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. The Lifegard Fluidized Bed Filter has been tested and proven to supply the highest level of effluent water quality and will respond quickly and efficiently to severe changes in ammonia levels caused by over feeding or the addition of too many fish at one time. To obtain highest water quality...a Lifegard Fluidized Bed Filter should be part of the system.

Construction: Rainbow’s quality molding and assembly presents a unique shape designed to actually hold more media than round tubes. Its flat back aesthetically brings the unit close to aquarium wall. The unit includes all necessary fittings for installation plus a self adjusting clamp, free standing base, and media.

Flow Control Valve: Simply turn the valve for adjustment of fluidization level. Can be removed to add media.

Water Fall Attachment: Increases oxygen level by spreading out a thin sheet of gently falling water.

Bottom Diffuser Plate: Lifts the sand bed evenly for perfect fluidization each time.

External Check Valve: Mounted externally for easy servicing. Prevents sand from clogging inlet pipe when power shuts off.

Top & Bottom Inlet Ports: Top inlet port allows easy installation to submersible power head pumps when unit hangs on aquarium. Two bottom inlet ports allow installation to a Lifegard Modular System or any in-line filter system when unit is installed inside aquarium cabinet. Two or more filters can be plumbed together with bottom inlet ports on each side.
