Well...actually, in this case (as in many others, I'm sure), I'd recommend a Rio 600 for you. LOL. I mean, you know it fits and you know its flow rate. Honestly, Rio powerheads are in fact really good for powered CO2 reactors. They're pretty no-frills, fit on well, and have a simplistic cube shape to them. However, a Rio 600 seems awfully powerful for a simple CO2 reactor. I'm using a Rip 50 myself and it works just great.
