Keep your planted aquarium supplied with a reliable source of pressurised CO₂ with these larger Colombo CO₂ cylinders.

Available in 800g or 1200g sizes, they are ideal for planted aquariums where you want longer running times and fewer bottle changes compared with smaller disposable CO₂ cylinders.

Choose your size

800g CO₂ Bottle
A good option for smaller planted aquariums or customers who want a larger CO₂ supply without moving up to the biggest cylinder.

1200g CO₂ Bottle
The better choice for larger aquariums, higher CO₂ usage or simply reducing how often the cylinder needs replacing.

Why choose Colombo CO₂ bottles?

  • Available in 800g and 1200g sizes

  • Longer-lasting alternative to smaller CO₂ cylinders

  • Ideal for planted and aquascaped aquariums

  • Suitable for Colombo pressurised CO₂ systems

  • Convenient disposable cylinders with no refilling required

  • Simple bottle replacement when empty

  • Steel cylinders can be recycled once completely empty

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).

Common Questions

Should I choose the 800g or 1200g bottle?

Choose 800g if space is limited, or 1200g for fewer bottle changes. The 1200g bottle holds 50% more CO₂, so it should last around 50% longer at the same usage rate.

Will this bottle fit my CO₂ regulator?

These bottles have an M10 x 1.0 connection and suit the Colombo CO₂ Profi system. The Colombo Advance 95g regulator needs the Colombo 95g-to-800g/1200g adaptor. Check compatibility before ordering; other regulator connections may need a different adaptor.

How long will a bottle last?

This depends on your bubble rate, daily running time and diffuser efficiency. There is no fixed lifespan for every aquarium. Choose 1200g if you want more time between replacements.

Can I refill these CO₂ bottles?

No. These are disposable, single-use cylinders. Replace the bottle when empty; do not attempt to refill it.

Is this a complete CO₂ kit?

No. This listing is for the CO₂ bottle in your selected size. You need a compatible regulator and the other equipment required by your CO₂ system.

How tall are the bottles?

Approximate height to the top of the pin is 28cm for the 800g bottle and 31cm for the 1200g bottle. Allow extra space above for your regulator and connections.
