This is a brilliant little device allowing anyone who currently uses the Colombo FloraGrow Nano CO2 set.

You simply screw this into your Colombo regulator (tighten with spanner first) and then screw in the larger 800g bottle. Simple as that and just think of the savings you can make now as the 800g bottles are SO MUCH more economical.

17mm diameter screw ring.

Can I use the 800g bottle with this adaptor on my tropica plant growth system nano 95g


Sadly no

Are you sure these adapters don't fit the tropica nano co2 kit which also uses 95G canisters? I thought most of these are standard? Please let me know. thanks.


Pretty sure but you’re welcome to try and return if it doesn’t

The diameter is 17mm

I don't know but probably- you're welcome try and return it if it doesn't fit 

Does the adapter fit the regulator from the Fluval 95g


Sorry we don't sell the Fluval 95g so don't know. You're welcome to try and if it doesn't fit return it.
