Diffuser Special M – 17mm acrylic-ceramic diffuser

This 17 mm CO2 diffuser is intended for aquarists who want a transparent, non-brittle diffuser for aquariums of 100–250 L. It is made with a ceramic fiber sinter rather than a standard ceramic sinter, and it has an acrylic body instead of glass or plastic.

Why it matters

• Ceramic fiber sinter: according to the manufacturer, the fibers are formed, sintered and pressed under high pressure before a second firing, producing finer and denser micropores than a conventional sinter.
• Acrylic body: unlike glass, acrylic is not fragile, and its transparency makes the diffuser hard to see in the tank.
• Compact 17 mm sinter: the smaller diameter is meant to reduce the diffuser's visual footprint among the plants.
• Bubble counter compatibility: the acrylic body allows a bubble counter to be mounted inside it.

Before first use, soak the diffuser in water for 10 minutes. If its output drops over time, the manufacturer recommends soaking it in bleach for 5 minutes.

What it works with

The diffuser is designed for CO2 systems in freshwater aquariums of 100–250 L, where it is fitted with its suction cups to the tank wall. Its 6 mm (4/6) connection works with standard CO2 tubing, and the tube length can be adjusted to suit the tank height.
