from what i have read, and from what Rex says on his build thread is that there is no media in the reactor. how long is your reactor? do you have a picture?
Reactor issues
I have a 5lb tank running my 55g, I decided to run my 40g off of it as well. So I just built my second reactor via http://www.rexgrigg.com/diy-reactor.htm and have a ton of bubbles coming through my filter return. Apparently I found out I inserted the co2 line at the bottom vs the top, but I did the same on my other and it works great. Anyway I flipped it upside down and swapped the filter lines and still bubbles. Anyone have any ideas what I could have possibly done wrong during the build? Do people put media inside? scoop me in =)

my reactor has bubbles coming out the return that float to the top. is that a bad thing?
Thats what I thought, why I didnt put media in mine. Mine is the standard 15 inches like in the build instructions. I know it is upside down in the pic, I reversed it to see if it would change anything. Might I add there are extra ball valves because I have another filter running that tank as well. Just not in the pic.
Yes it is a bad thing.... Essentially every bubble is wasted co2. If it is one bubble every here and there it is probably not an issue because most of it is being absorbed.my reactor has bubbles coming out the return that float to the top. is that a bad thing?
I inject my CO2 via inline venturi before the reactor. Even if some of the tiniest bubbles make it out of the return, they move erratically downwards about one inch every 2 seconds through a 36" reactor. If you have high waterflow, injecting into the bottom of the reactor may not be a good idea, as the bubbles may not be able to rise against the water flow. There's kind of a balance that must be struck between losing some CO2, and not building a pocket of gas in the top of the reactor.
How do you have this routed? It looks like the CO2 goes straight in the top of the reactor. I have the intake on my reactor on the top, the gas on the side, and the out on the bottom. I don't have bubbles.
