Aqua-Noa CO2 filter diffusor 3 in 1

Aqua-Noa CO2 Filter Diffuser 3 in 1

With the Aqua-Noa CO2 Filter Diffuser 3 in 1, adding CO2 becomes very easy. This diffuser is placed directly onto the external filter hose. As a result, CO2 is immediately mixed with the water and introduced into the aquarium via the outlet.

By adding the CO2 directly into the outlet, you ensure that the CO2 is distributed throughout the entire aquarium. Another advantage is that the diffuser can be placed in the cabinet next to the filter & CO2 system, making CO2 addition completely invisible in the aquarium!

The Aqua-Noa CO2 Filter Diffuser 3 in 1 also comes with an integrated bubble counter and check valve. The bubble counter is filled with water, making it easy to count bubbles and adjust the CO2 system. The built-in check valve protects equipment such as CO2 adapter, pH controller, and solenoid valve from aquarium water backflow.

The diffuser has plastic nuts to secure the hoses, ensuring they cannot come loose easily!

Available for 3 hose sizes:

• 12/16 millimeter hose
• 16/22 millimeter hose
• 19/25 millimeter hose

Includes suction cups for attachment to the glass or inside the cabinet.
