This Mini Glass CO2 Diffuser is perfect for the nano or small aquarium and produces tiny streams of bubbles that rise slowly from the ceramic disk. This means that the CO2 has a longer time to dissolve which makes efficient use of your CO2 supply.
This diffuser is easy to install and clean, is suitable for aquariums up to 120 litres, has a 1.5cm diffusing area and works with pressurised CO2 systems.
