Does anyone make an external reactor designed for 16/22mm pipes

Does anyone make a decent quality external reactor designed for 16/22mm pipes ?

Sera co2 reactor 500 or 1000 are good quality, you'll need a large amount of flow to get them to work well.

ring the green machine.... the AM100 is a great reactor and was always 16/22 before, this may be a typo on the new website.

Any reactor used for marine tanks will be perfect.

I think this may have changed as it is also listed here as 12/16mm http://www.swelluk.com/aquarium/co2...ic-reactor-1000-external-co2-diffuser-87.html

You can leave them as they are and just put the 16/22 over them as they are stepped. Or you can cut off the 12/16 part of the barb with a hack saw and open up the hole with a 12mm or 1/2" drill.
