Diffuser Original Extend L white – 25mm CO₂ diffuser for aquariums

This CO2 diffuser suits aquarists running planted tanks from 200 l who want a clear, sturdy diffuser that can be fitted to their own aquarium setup. The ceramic membrane produces fine gas bubbles, and the bendable tube lets you position the unit without extra fittings.

Why it matters

• The ceramic membrane releases CO2 as fine bubbles, which dissolve more readily in water.
• The acrylic body is transparent and far less fragile than glass, so it is less likely to crack during handling or cleaning.
• The tube is about 38–40 cm long and can be cut to length, then bent by gently warming it, to form a knee over the tank edge.
• The set includes two suction cups for mounting and extra tube pieces for practising the bending before fitting the main unit.

What it works with

The diffuser is intended for CO2 systems in aquariums from 200 l and fits standard 6 mm (4/6) tubing, so it connects directly to typical CO2 setups. Its length allows it to be routed along the rim of the tank, which keeps the equipment out of the main aquascape.
