As another option for the Aqua-medic 1000 co2 reactor, is the Aquamas reactor range from Germany, they all have the 16/22mm connection which we need.
I bought mine, and have to say it is off excellent quality, and i have no problem with co2 diffusion across my tank.
It also has the important vent pipe to bleed / prime the appliance at setup, which some models do not include.
Here is a link to there site, you will have to register, then drop them an email (in english), detailing what you require. All payment is done through paypal, then wait for a few weeks. Packaging is excellent too.

And here is my tank with hydor heater and reactor fitted, there are a few picures there.

The unit he has is around 90 euros & postage to the uk is 19 euros,I emailed them yesterday (in English)-it looks an awesome piece of kit, I think they could also help with different size inlets/outlets but my German is a little rusty!
