Lee's Undergravel Filter 40/55 Gallon

Lee's Undergravel Filter is the key to providing a strong biological filtration system. 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. Designed with adjustable 1" uplift tubes for better water circulation. Multiple plate construction for easy installation. Includes airline diffusers and carbon cartridges and has a fish-saver feature. Advance design allows separate plate installation and features optional flow-thru set-up which can be used with a power head. Made of special quality plastic which resists splitting and cracking. Contains four each: under gravel plates, connector rings, uplift tube assemblies, airline tubing with connectors, air diffusers with connectors and disposable carbon cartridges. For use in freshwater and saltwater aquariums. For 40/55 gallon aquariums 12" x 48".
