I've had a problem getting my co2 levels up in my 20 gal using the HOB filter as a diffusor. I thought I would try to make a reactor. It's powered by a maxi-jet 600 (160 gph). I couldn't really find anything like bio-balls to put in it, but I filled it 1/4 full of tile spacers. I have not had a chance yet to use it really, just a trial in the kitchen sink to check for leaks. It's not much to look at but hopefully it will do the job.
