How To Get Co2 Into External Filter?

[nry]

Is there any special method of getting CO2 to pass into my external filter (TetraTec EX600)? It would be nice to find a little adapter which accepts a 12mm hose on each end and a standard airline sized tube into the side but I am guessing this doesn't exist? I assume I need to alter the intake tubing somehow but I'm not entirely sure how to do this to guarantee no leaks

So you'll be wanting an in-line CO2 reactor then?

A Rhinox in the tank below the intake is preferred over the use of reactors though I believe. I could be wrong, never used them....

I was aiming on using the filter as the reactor, I'll barely need to add many bubbles in comparison with the diffuser I use now (and the Juwel internal filter) - I know others have done this but I'm not sure how.

All I do is place the ceramic diffuser directly below the filter intake. Injecting the bubble straight in to the filter without diffusion first may have an effect on your impeller.

Apparently, there have been cases of the CO2 levels causing the cannister seals to perish, but I have had no problems so far. Eheim frown on the practice.

You could probably fabricate something like you are after quite easily. The most common method though is just to insert the Co2 tubing directly into the filter inlet, it may require a bit of force to get it through the grill. I used to do it that way and it worked great.

Hmm, I have some nice (fragile!) glass lily pipes, I don't fancy trying to squash a tube through the small grills

I reckon a trip around a local DIY store is in order - I'd love an external reactor but let's just say budgets are now a tad tight
