Colombo Adaptor Ring

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.
