Product Description
The Lifeguard Fluidized Bed Filter is a high capacity biological filter for fresh or saltwater aquariums. Beneficial bacteria attach to the media within the 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 attach to the media and draw in oxygen, supplied by Rainbow's exclusive water fall device and other required nutrients from the passing water, converting ammonia and nitrites to relatively harmless nitrates. The sand grains are in continual free fall throughout the water resulting in an excellent transfer capability between the liquid and the bacterial film on the media. 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 FB300 is rated for aquariums up to 300 gallons. It is most effective at low flow rates. Lower flow rates increase the contact time between the bacteria and the toxic ammonia and nitrite compounds that they utilize.

Difficult to use.,
By
This review is from: Lifegard FB300 Fluidized Bed Filter - Up to 300 gallons - 8 in. x 3 in. x 17 in. (Misc.)
This filter worked well when it worked. You need a separate power head to run the Lifeguard. I had great difficulty getting the Lifeguard going again everytime I cleaned the power head and hooked it back up. I ended up getting rid of it - too much hassle. They need to provide a dedicated, matched powerhead and connections - the list in the instruction manual of compatible units is not accurate!

Would Be Great Except For Stupid Design Flaws,
By Steven Metz (Pennsylvania, USA) - See all my reviews
This review is from: Lifegard FB300 Fluidized Bed Filter - Up to 300 gallons - 8 in. x 3 in. x 17 in. (Misc.)
This would offer an immense amount of biological filtration for the dollar except for two stupid design flaws. First, anytime the power goes off and the filter loses flow, the sand fills up the input tube. This requires removing the sand through the hole in the top and replacing it the same way, which is an extraordinarily tedious task. Second, the seal on the bottom is very poor quality. I've had two develop leaks, one right out of the box. Lifeguard probably saved a dime in manufacturing costs and the result was a very bad product. Dumb, dumb, dumb.

Can NOT handle pressure,
By
This review is from: Lifegard FB300 Fluidized Bed Filter - Up to 300 gallons - 8 in. x 3 in. x 17 in. (Misc.)
In the last two weeks I've had 2 of these leak from the seam on the bottom of the filter. It does a GREAT job of biological filtration but with any significant pressure load it leaks. I was running it on the return side of an Ocean Clear canister powered by an 800gph little giant pump. It cant take that basic pressure so sadly I cant use it. It might be better suited to running off a lower flow powerhead but since my tank is drilled in the bottom I have no use for this since I don't want to run something up top that would obstruct the view of the tank. Too bad it's not more sturdy it would have made a great addition to my filtration.
