Diffuser M – 17mm acrylic and ceramic CO₂ diffuser

This diffuser is for aquarists running CO2 injection in tanks of 150–250 L who want a small, clear diffuser that does not break easily. It is built around a 17 mm ceramic fibre sinter and an acrylic housing, and the package includes a large suction cup for mounting.

Why it matters

• Ceramic fibre sinter: according to the manufacturer, fibres are formed from ceramic mass, sintered and then pressed and fired again, producing micropores that are smaller and more numerous than in a standard ceramic sinter.
• Acrylic body: the housing is transparent and, unlike glass, does not shatter, so the diffuser is less exposed to damage during handling and cleaning.
• Internal bubble counter: the transparent acrylic body allows a bubble counter to be placed inside the diffuser, so CO2 flow can be checked visually.
• Compact 17 mm size: the manufacturer states that the smaller sinter size is meant to keep the diffuser less prominent in the aquarium, leaving the plants as the main visual element.

What it works with

The diffuser is intended for freshwater planted or CO2-supplemented aquariums in the 150–250 L range, using a standard 4/6 mm hose from a CO2 regulator or cylinder setup. Its compact sinter and transparent housing make it suitable for tanks where the diffuser should stay visually discreet. Compatibility with other tank sizes or CO2 setups is not specified in the product data.
