Eheim Adjustable Fish Aquarium Air Diffuser

Help improve your aquarium water’s oxygenation with the Eheim Adjustable Fish Aquarium Air Diffuser! Great for saltwater and freshwater aquariums, you can mount this diffuser at the end of the outlet hose, close to the surface of the water and fixed on the tank wall. This creates an injection angle (which is as flat as possible), and helps create movement within the water. You will place the diffuser's air hose outside the aquarium and you can dose the amount of sucked air using the enclosed pressure adjusting clamp. The diffuser mixes the supplied air flow with return water, which is injected under the surface of the water with the pressure of the filter pump.
