ADA Bell Glass Mini CO2 diffuser

The Bell Glass Mini is a glass CO2 addition device designed to efficiently add CO2 into an aquarium, modeled after the shape of an upside-down gentian (bellflower in English) flower. The air bubbles released from the L-shaped tube inside the main unit function as a counter to measure the droplet amount, which is a guide to the amount added. It uses a storage method, and as the inside of the main body is filled with CO2, it is slowly added to the water, preventing excessive addition of CO2, which tends to occur in small aquariums.
