NEO Diffuser Extended Special L CO2 Diffuser 25 mm

NEO Diffuser Extended Special L is a CO2 diffuser with a clear acrylic body and a 25 mm membrane of sintered ceramic fibres that produces very fine CO2 bubbles. It is designed for aquariums of 250–500 l and connects to standard 4/6 mm CO2 tubing.

The diffuser's acrylic tube, about 40 cm long, can be cut to length or softened with heat, for example a lighter flame, and bent into a hook over the aquarium rim. That way you decide where the bend sits and which glass thickness it fits. Two extra tubes for practising the bend are included, plus two large suction cups with a hole for the tube. Before first use, soak the diffuser in water for 10 minutes.

• Very fine CO2 bubbles
