Used Eheim Air Pump Air200.

Eheim Air Pump 200 (2 x 100) l/h, has two individually adjustable air outlets and comes equipped with two new Eheim diffusors and one used diffusors.

The air flow can be regulated at each outlet on the pump and also on each diffusor. This allows you to set your own individual bubble effect.

Vibration dampening rubber edgings contribute to the pump’s quiet operation. The air pump stays still and doesn’t “wander about”. You can also hang it vertically on the aquarium glass by the hook that comes with the air pump.

Features:

• Very quiet operation
• Long service life, best quality
• Airflow adjustable at each air outlet on the device
• Additional adjustment of the air flow and bubble effect using the diffusor
• Completely equipped with 2 air diffusors and 2m airline
• Rubber suction pads to dampen vibration
• Hook for hanging vertically

Note: This air pump is so quiet that I don’t even know it is running!
