Though small in stature, Fluval Spec is big on features. It comes with a sleekly-designed overhanging lighting system, consisting of 31 powerful LED lamps, that arches above the aquarium to provide brilliant illumination for plants and d cor. The aquarium includes a powerful circulation pump with adjustable output nozzle and a large 3-stage filtration system that provides more than enough filtration for ultra clean and clear water. It also comes with all the necessary filter media: a porous foam block with convenient handle, activated carbon, and BioMax bio rings for effective and thorough mechanical, chemical, and biological filtration. The pump and filtration system are conveniently located in a separate chamber at one end of the aquarium to simplify maintenance.
