I'm brainstorming a mini internal co2 reactor for distributing the DIY co2 on my 10 gallon, and I was wondering if it would work sufficiently well to modify a cheap internal filter to act as a co2 reactor/diffuser. Would I be better off with just a cheap/small powerhead? As far as an internal filter, I was thinking of something like This one or This one...

Get a Via Aqua 180

Get a Lees elbow and attach it to the co2 line

snip a small piece out of one of the intake vents and shove the Lees elbow into the vent, you want a tight fit. You don't even need to glue it, just keep tension on the co2 tubing and tie the co2 line to the power cable.

It gives a nice mist of co2 shooting out the exit. For about $15.00 you are good to go. The only thing that annoys me is the sound of the co2 bubbles hitting the impeller so, turn up the TV.

Hmm, so far I like the design of the reactor people have built based on the design from the Barr Report site, but I'm still slightly confused as to the exact steps to build it... still researching though...

Tom Barr's design was what gave me the idea for the one I used. I did try using a Rio 180, the same one he described and tried modifying the impeller the same as he described. But the plastic was to hard and just snapped when I tried to cut it. After I boogered that one up, I decided to buy the Via Aqua because of price and size, easy to hide.

Yeah, you can use any power head or water pump. You just have to find a way to aim the co2 bubbles at the impeller.
