Pro-SE Series Complete Kit is a compilation of our most popular dual stage Pro-SE CO2 regulator and latest inline CO2 diffuser.

This kit will come with everything you need to start injecting CO2 via external canister filter.

The dual stage constructions minimise the increase in output pressure as pressure drops in the gas cylinder and will prevent end-tank-dump keeping your aquarium livestock safe and CO2 levels constant.

The regulator is available in two thread standard :

  • CGA320 for North America
