Our CO₂ accessories.

Colombo offers a wide variety of products for producing, measuring and regulating your CO₂ systems.

CO₂ Reactor Refill

Make your own CO2 with 2 components. No more changing pressure bottles! How does it work? Open the cylinder and add the 2-components and 300 ml of water, close the bottle with the pressure regulator, the chemical reaction creates around 105 grams of CO2 gas in 30 minutes. 1 pack is thus sufficient to make about 315 grams of CO2.

CO₂ Indicator

The CO2 indicator is an indispensable tool when using a CO2 system. The indicator shows the CO2 value, so you know how much CO2 is in the aquarium water and can adjust the CO2 system to the correct amount.

CO₂ Solenoid Valve

As plants only absorb CO2 during the day, the supply can be stopped at night. By installing the solenoid valve, this can be done automatically using a time switch. The solenoid valve pays for itself, as you save a lot on CO2 cylinders!
