Actually, the only thing new is the powerhead 
After hearing all this reactor talk and seeing the nagging BBA in my tank even after massive amounts of CO2, I had to put one together. It's made from a Rio 600 and a gravel vac I had laying around. After making the connections, I fired it up. I've yet to add the venturi feature. I just want to watch the bubbles for awhile
About the venturi: Do I need one? The tube is a good 12" long, and a few small bubbles escape the bottom and rise up. However, I have a Hagen 802 powerhead with the quickfilter attachment hanging right next to the reactor. Since I turned turned on the reactor, the 802 is spraying an ultra fine mist of CO2 all over the tank. It never sprayed bubbles before.
Anyhow, if I add a venturi, I think there are a couple of ways I could do it, and possibly do it more effectively than returning it into the reactor. One way would be to run a tube into the outlet on the 802. There is an inlet on the outlet ( ) which is usually used to inject air. Another way would be to run a tube into the quickfilter (pre-impeller smashing). Another way still would be to run a line into the intake of my Eheim 2028. I figure that way would give the CO2 the most dwell time. Then of course I could just run a tube into the spraybar.
Suggestions?
