The under gravel filter uses the gravel as filtration mediathus providing mechanical and biological filtration since the beneficial bacteria usually makes colonies on objects, instead of just floating around in the water like the malicious types; the gravel is perfect for vast colonies of beneficial bacteria.
A substantial layer of gravel can act as a mechanical and biological filter media in aquarium set-ups called undergravel filters. At its most basic set-up an undergravel aquarium filter is simply a rectangular grating or plate that sits under a gravel substrate and pulls water down through this substrate, thereby performing mechanical filtration and offering a vastly larger site for beneficial bacterial colonies to thrive.
