Eheim Diffuser for Aquarium Filter Hose - Adjustable Air Diffuser

The Eheim Diffuser is an air diffuser accessory that attaches to the outlet hose of an external filter or pump to add oxygen to aquarium water. It draws in air from outside and releases it into the water as fine bubbles, making it a good fit for densely stocked tanks, lightly planted aquariums, and cold or marine setups.

It fits 12/16 mm and 16/22 mm standard hose sizes and is controlled by an adjustable clamp for precise air flow.
