Diffuser Special Normal S CO₂ + Clip White – diffuser + CO₂ elbow for a 12mm aquarium

This white-membrane CO2 diffuser is intended for hobbyists running planted aquariums of 20–100 l who want a compact diffuser that stays out of sight. It comes with a U clip that routes the CO2 hose over the tank rim, so the hose does not need to be run down the glass.

Why it matters

• Ceramic-fibre membrane: the 12 mm membrane is made from ceramic fibres rather than traditional sintered ceramic, with microchannels of smaller diameter and higher density.
• Fine bubbles: according to the manufacturer, these microchannels release ultra-fine CO2 bubbles, which improves gas dissolution and, per the supplier, lets the same CO2 supply be used more efficiently.
• Compact body: the diffuser is smaller than typical models, which the manufacturer states keeps efficiency comparable to larger units while reducing its visual footprint and leaving more room for plants and décor.
• Transparent acrylic body and U clip: the body is fully transparent, and the included U clip (Neo Clip) holds glass up to about 12 mm thick, reducing the problem of suction cups detaching.

What it works with

The diffuser is designed for freshwater planted aquariums in the 20–100 l range that are fitted with a standard 4/6 mm CO2 hose and a CO2 supply. Its 16 cm height and 12 mm membrane suit smaller and medium tanks, and the shortenable tube allows the unit to be adjusted to the tank depth.
