Lees Original Undergravel Filter 60 Long x 15 Wide or 72 Long x 12 Wide (90-100 Gallons)

Lees Under gravel Filter is the key to providing a strong biological filtration system. Aquarium under gravel filters utilize your tank's gravel substrate as a filtering surface area while providing oxygen to help aerate your aquarium water.

• Provides biological filtration and aeration to aquarium
• Includes airline diffusers, carbon cartridges, Discard-A-Stone, and fish-saver feature
• For use in fresh and saltwater aquariums
• Must be attached to an air pump or powerhead (sold separately)

Placed on the bottom surface of the aquarium, the filter plates utilize the gravel bed as a source of surface area for bio-filtration and provide oxygen by recirculating the water down through the media and up through the uplift tubes. The advanced design allows separate plate installation and features an optional flow-thru setup, which can be used with a powerhead. Adjustable 1" uplift tubes provide superior water circulation. The filter is made of special, premium quality plastic that resists splitting and cracking.
