Lee’s Premium Under Gravel Filter – 75/90 gal

Lee’s Premium Under Gravel Filters clean your freshwater or saltwater aquarium through a biological filtering process which supports the growth of beneficial bacteria. This allows natural detoxification and maintains proper ammonia balance by circulating water flow through the gravel bed. They also include 2 Premium Carbon Cartridges, coarse Discard-a-Stones, a fish-saver elbow, and a telescoping ring to easily adjust the uplift tube height. It is constructed with a strong multi-level UGF plate design with molded gravel guards to prevent gravel from entering the uplift tube. In order to maximize water quality, Premium Under Gravel Filters work entirely with a power filter.
