Diffuser Special Curved S Clip – 12mm CO₂ diffuser with elbow

This clip-on CO2 diffuser is intended for planted freshwater aquariums up to about 100 l, where a compact unit that fits on the glass edge is needed. Its built-in elbow replaces a separate bend in the hose, so the CO2 line can run straight to the diffuser.

Why it matters

• Ceramic fiber membrane: the 12 mm membrane is made of ceramic fibers with very small, densely packed microchannels, which produce ultra-fine CO2 bubbles.
• Integrated elbow: the shaped tube works as the edge elbow, so no additional fittings are needed and the hose is not kinked.
• Clip mounting: the diffuser attaches to glass up to about 12 mm thick, supported by two suction cups included in the set.
• Acrylic body: the body is fully transparent and, according to the supplier, more resistant to breakage than glass, which keeps the unit nearly unnoticeable in the tank.

What it works with

The unit is matched to small and medium tanks up to about 100 l that use a standard CO2 system with a 4/6 mm hose. Its compact size leaves more room for plants at the back and front of the tank, and it fits with typical planted setups where discreet CO2 delivery is preferred.
