Lee's Undergravel Filter is the key to providing a strong biological filtration system. Undergravel filters utilize your tank's gravel substrate as a filtering surface area while providing oxygen to help aearte your aquarium water.
Placed on the bottom surface of the aquarium, the filter plates utilize the gravel bed as a source of surface area and provide oxygen by recirculating the water down through the media and up through the uplift tubes.
