This Seachem Glass Bubble Counter Diffuser is a highly effective way to disperse CO2 throughout your planted aquatic system. The pollen-style diffuser is compatible with 6 mm (1/4") standard airline tubing and connects directly to CO2 injection systems. The sleek, low profile unit helps to minimize visual distractions within the tank and boasts a 23 mm large surface area disc that provides diffusion for large volumes of CO2 gases. The built-in spiral bubble counter allows for easy monitoring of the CO2 injection rate. Suction cups included with the unit.
Well suited for aquariums between 20-90 gallons.
The stem is very delicate& easily broken. If the white disk accumulates algae a light scrapping on the disk surface & it is as good as new. Have them on COw systems on all 6 aquariums.
