Lees Under Gravel Aquarium Filter is the key to providing a strong biological filtration system. Trouble-free Biological Filter designed with adjustable 1" uplift tubes for better water circulation. Multiple plate construction for easy installation. Includes airline tubing and Discard-A-Stone and has a fish-saver feature.
Placed under the gravel on the bottom surface of the aquarium, the filter plates utilize the gravel bed as a source area and provide oxygen by recirculating the water down through the media and up through the uplift tubes. 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. Available in 3 different styles to fit rectangular, hexagonal, octagonal, and flatback aquariums.
For use in freshwater or saltwater aquariums.
