Compatibility

These cylinders are designed for use with compatible Colombo CO₂ regulators and systems.

Some Colombo systems may require an adaptor depending on the regulator and cylinder connection being used, so always check your existing CO₂ setup before ordering.

Which size should I choose?

For most customers, the decision simply comes down to space and how frequently you want to replace your CO₂ bottle.

Choose 800g if you want a good balance between capacity and cylinder size.

Choose 1200g if you use more CO₂ or want the longest possible running time between bottle changes.

The actual lifespan of either bottle will vary depending on aquarium size, bubble rate, daily operating time and how efficiently the CO₂ is diffused.

Approx height to top of pin 28cm (800g) and 31cm (1200g).
