CO2 diffuser M – CO2 diffuser for aquariums

This CO2 diffuser suits keepers of planted freshwater aquariums up to 120 L who want to feed carbon dioxide through a compact, low-profile unit. It fits 4/6 mm tubing and is designed to sit inside the tank without drawing attention to itself.

Why it matters

• Fine bubbles: according to the supplier, the diffuser produces considerably smaller bubbles than traditional glass diffusers, and these rise slowly through the water column.
• Gas dissolution: the supplier states that the diffuser dissolves CO2 bubbles efficiently in the water.
• Small footprint: at 19 mm in diameter and 6.5 cm high, the unit takes up little space, and the clear acrylic body is meant to look like glass.
• Impact resistance: made of acrylic instead of glass, the diffuser is lighter and less prone to breaking when dropped or cleaned.

What it works with

The M size is intended for aquariums up to 120 L and connects to standard 4/6 mm CO2 tubing from a CO2 system. Use it in planted freshwater tanks where a controlled CO2 supply is needed, and mount it with the included suction cup at a point where the bubble stream can rise through the water.
