This is what I use I had another brand that I constantly had to futz with my co2 and it used so much of it that my ph would fluctuate too much and it drove me a little mad until I replaiced it with http://www.marinedepot.com/aquarium_calcium_reactors_knop.asp?CartId= Really happy with it and it but, other may have had good luck with other brands. It's easy to use and adjust.
