ISTA 3L CO2 Aluminium Cylinder Set

ISTA CO2 Aluminium Cylinder Set lets you dose carbon dioxide on demand into your planted aquarium. The set comes complete with full accessories including stainless steel guage CO2 controller.

A reliable source of carbon dioxide is critical to ensure a vibrant planted tank, with clear water and active frolicking fishes. This is because carbon dioxide is required for photosynthesis. Insufficient CO2 stunts the growth of aquatic plants, causes leaves and stems to become pale and triggers algae growth.

The ISTA CO2 Aluminum Cylinder Set is easy to setup. In just a short moment, you can start bubbling carbon dioxide into your aquarium water.

The cylinder contains liquefied CO2. The stainless steel twin gauge CO2 controller gives you precise control of the CO2 dosage output into your tank.

ISTA CO2 cylinder system is TUV-approved for added safety assurance.


  • Seamless aluminum CO2 cylinder, TUV/DOT approved, safety and quality assured.
  • Precise pressure reduced regulator provides accurate and reliable CO2 output.
  • Stainless steel twin gauge CO2 controller provides accurate and reliable CO2 output.
