Nano CO2 Diffuser L – acrylic CO2 diffuser

This CO2 diffuser is intended for aquarists running aquariums above 200 L who want a compact, transparent unit that dissolves CO2 without drawing attention away from the plants. Its ceramic fiber sinter and acrylic body address the common trade-off between glass diffusers, which are fragile, and plastic ones, which look less refined.

Why it matters

• The ceramic sinter is made from fused ceramic fibers rather than a conventionally fired ceramic mass, which the manufacturer states produces finer, denser pores.
• The total height of 8.5 cm keeps the diffuser low in the tank, so it takes up less space than a taller unit with the same sinter size.
• The acrylic body is transparent and resistant to breakage, a more durable option than glass.
• A bubble counter sits inside the body and remains visible, so the gas flow can be monitored at a glance.

Specifications

• Recommended aquarium size: above 200 L
• Sinter diameter: 23 mm
• Total height: 8.5 cm
• Body material: acrylic
• Tubing connection: standard 6 mm (4/6)

What it works with

The diffuser is sized for larger aquariums above 200 L and connects directly to standard 6 mm (4/6) CO2 tubing, so it fits typical CO2 setups with a regulator and solenoid. Its 23 mm sinter and compact height make it suitable for placing in the substrate area or behind plant groupings in the aquarium.
