Diffuser Special Curved M Clip – 17mm CO₂ diffuser with elbow

This white acrylic CO2 diffuser suits keepers of medium-sized aquariums who want a dissolved-CO2 system that stays discreet inside the tank. The 17 mm membrane and the integrated elbow address two common issues: low gas dissolution efficiency and a CO2 hose that is awkwardly routed over the rim.

Why it matters

• The membrane is made of ceramic fibers rather than standard ceramic sinter. According to the manufacturer, this produces very fine micro-channels and fine CO2 bubbles, which improves gas dissolution.
• The profiled tube works as an elbow at the aquarium edge, so the CO2 hose runs without sharp bends.
• The clip hangs on the glass and holds steady on panes up to about 12 mm thick. Two suction cups are included.
• The body is transparent acrylic, which the manufacturer describes as more impact-resistant than glass. Its 28 cm length and 17 mm membrane keep the installation compact.

What it works with

The diffuser is designed for medium-sized aquariums in the approx. 100–250 l range. It connects to a standard 4/6 mm CO2 hose, so it works with typical CO2 setups that use this tubing size. Its clip fits glass up to about 12 mm thick.
