CO2 Glass Diffuser (Medium)

Description High quality glass diffuser creates a fine mist of CO2 in the aquarium for absorbtion by plants. As CO2 bubbles pass through the porous diffuser, they are diffused into streams of tiny bubbles. With increased surface area, the tiny CO2 bubbles are readily dissolved into the water, increasing the saturation of CO2 in the aquarium ecosystem. Best placed in direct line of flow, usually at the oposite end of the tank to where the filter outlet is positioned. This will ensure your flow pushes the bubbles downwards to keep them in your aquarium longer, aiding diffusion. Size: Outer: 3.5cm Inner: 2.5cm Height: 9cm
