Colombo CO2 Adaptor Ring 95g to 800g/1200g

Installed this adaptor to connect an 800g bottle to my existing nano CO2 setup, and it threaded on perfectly with no leaks. The brass fitting feels solid and secure, making the swap from the small 95g canisters effortless. My plants are getting consistent CO2 now without the constant refills.

Was a bit skeptical if this would actually fit my existing setup, but the threading matched perfectly with my Tropica system. My 800g bottle now runs for over a month instead of swapping those tiny 95g canisters every week.

Finally ditched the constant bottle changes on my nano setup by threading this onto an 800g tank instead of the little 95g ones. The ring screws in snug with no leaks, and refills now last me months rather than weeks.
