CO2 Cylinder Tanks

Build your planted aquarium CO2 setup around a Week Aqua steel cylinder. These CO2 Cylinder Tanks provide the gas supply for a system assembled with a compatible regulator, CO2 tubing and diffuser, giving you a choice of two capacities for your equipment arrangement.

Select the size that fits your setup:

• 5LB Tank: model CO2-SC-2L.
• 10LB Tank: model CO2-SC-4L.

The capacity names above identify the supplied options. Match your regulator to the cylinder's valve connection when putting the system together, and consider the available equipment space when choosing a size.

Complete the gas line with Week Aqua CO2 Tubing and choose an inline CO2 diffuser for compatible filter plumbing. A CO2 Drop Checker Kit provides a useful visual reference as you establish your planted aquarium's CO2 routine.
