The JBL Vario CO2 Diffuser shares the CO2 throughout your aquarium evenly and carefully to effectively benefit plants and fish.
The unit can be extended by the modular extension unit (available separately), and can easily be taken apart for cleaning. The unit can be used with virtually any CO2 unit to ensure that all of the tank receives the right amount of carbon dioxide.
A secure lid on the canister ensures that not a single bubble of CO2 is wasted.
A separate bubble counter or pump drive are not required, saving both cost and space in your aquarium. Keep an eye on the KH level to monitor the level of CO2 required. A JBL KH Test Kit is ideal.
The extension pack contains 5 separate modules which can be used to build the desired unit and increase the supply of CO2. Increasing the capacity by 100 litres at 10⁰ dKH or 200 litres at 4⁰ dKH.
- Suitable for aquariums up to 200 litres (8" high and over)
- Secure cap prevents loss of CO2
- Extensions available for bigger tanks

To monitor the pH, we recommend the JBL Test Set Permanent CO2 plus pH. The bubble path can be extended by inserting any number of extension sets (MC112).
