FZONE Mini CO2 System

I've got this FZONE mini CO2 system that I never ended up using. It's designed for planted aquariums and works with both 3/8" and 5/8" disposable CO2 cartridges. It's still in the original box and includes the regulator with a built-in pressure gauge. Great little setup if you're looking to add CO2 to a smaller tank without a bulky tank. CO2 cylinder included.
