Inside the diffuser, the built-in bubble counter allows you to see how many CO₂ bubbles are released in a given time.

With the adaptor available as an accessory, you can upgrade this set and use a large 800 or 1200-gr CO2 cylinder.

Begin with our Colombo CO₂ Advance kit

Start with the CO₂ Advance kit, equipped with a 95-gram cylinder, Pressure regulator
and 3-in-1 diffuser, which is ideal for aquariums up to 100 liters.

Enhance efficiency with a CO₂ Indicator

Enhance the the CO₂ Advance kit with various options. One such option is employing a CO₂ indicator, providing real-time monitoring of CO₂ levels in your aquarium. This ensures optimal CO₂ levels, preventing overuse and optimizing the kit’s efficiency.

Stop CO₂ wastage with a Solenoid Valve

Another recommended accessory is a Solenoid, a magnetic valve that opens and closes in combination with a standard timer. This allows you to halt the CO₂ flow at night when plants don’t require it, effectively doubling the lifespan of your CO₂ cylinder.

Upgrade with adapter ring to larger CO₂ cylinders

Our exclusive adapter ring lets you use 800g or 1200g cylinders, extending usage time and enabling application on tanks up to 400 liters. Switching to these larger cylinders reduces change frequency, potentially saving up to 70%. Attach the ring to the regulator and screw it onto a large cylinder for enhanced efficiency.
