Diffuser Original S CO₂ + Clip White – CO₂ diffuser + 12mm aquarium elbow

This diffuser suits keepers of planted aquariums up to about 100 l who want to add CO2 without a bulky diffuser in the tank. The small 14 cm body with a 12 mm membrane leaves more room for plants and décor, and the fitting connects to a standard 4/6 mm CO2 hose.

Why it matters

• Microporous ceramic membrane: it releases very fine CO2 bubbles, which the manufacturer states dissolve better in water and raise efficiency at a lower CO2 consumption.
• Acrylic body: high-strength transparent acrylic that the manufacturer describes as more impact-resistant than glass, so it is less prone to cracking.
• U clip (Neo Clip): guides the hose neatly over the tank rim and helps prevent it from kinking.
• Two suction cups included: used to fix the diffuser in position inside the tank.

What it works with
