Aquarium CO2 Diffuser for Planted Tanks, Clear Acrylic In-Tank Design and Replaceable Ceramic Membrane

Keep CO2 delivery efficient in your planted aquarium while maintaining a clean, unobtrusive aquascape. This in-tank diffuser uses a porous ceramic membrane to release CO2 as streams of tiny bubbles, allowing the gas to dissolve readily for aquatic plants.

The small, transparent acrylic body blends into the aquarium, while two included suction cups hold the diffuser steadily against the glass. Choose the size suited to tanks below or above 40 gallons (150 litres).

Key Features

• The Nano CO2 Mist Technology ceramic membrane releases CO2 through a porous surface as tiny bubbles, supporting ready dissolution in the water for planted-tank care.
• Efficient absorption means more of the injected carbon dioxide can reach aquarium plants and less is wasted during regular use.
• Its compact, transparent acrylic body stays discreet among plants and hardscape, keeping attention on the aquascape rather than the equipment.
• The replaceable ceramic membrane is easy to reinstall, making ongoing diffuser upkeep straightforward.
• Two included suction cups provide stable positioning on the aquarium glass, so the diffuser remains where it is placed.
