Nano CO2 Diffuser M – acrylic CO2 diffuser

This diffuser is intended for planted tanks between 100 and 200 litres, where the hobbyist needs CO2 dissolved efficiently without a bulky or fragile part in the aquarium. It combines a ceramic fiber sinter with an acrylic body, so the unit is more durable than glass and less conspicuous than many plastic models.

Why it matters

• Ceramic fiber sinter: the fibers are formed with an electromagnetic pulse process and fired under high pressure, which the manufacturer says produces micropores of smaller diameter and higher density than a conventional ceramic sinter.
• Compact construction: the manufacturer states that the sinter technology allows a smaller diffuser to reach the same efficiency, and the 8.5 cm total height keeps it from competing with the plants.
• Acrylic body: the body is clear, so the diffuser is hard to notice in the tank, and it is more resistant to damage than glass.
• Visible bubble counter: the counter sits inside the transparent body, so bubble rate can be checked at a glance.

Specifications

• Aquarium volume: 100–200 L
• Sinter diameter: 17 mm
• Total height: 8.5 cm
• Hose connection: standard 6 mm (4/6)
• Body material: acrylic
• Bubble counter: built in, visible through the body

What it works with

The diffuser is matched to aquariums of 100–200 L and to setups where the plants are the main decorative element. Its standard 6 mm (4/6) hose connection means it works with the common CO2 tubing used in this range of planted tanks.
