it is all about surface area. With a bell diffuser, you have a MUCH MUCH smaller surface area of CO2 than with a bunch of tiny bubbles. Also, with a reactor, you constantly have fresh water to saturate with CO2. With a bell diffuser, the water across the CO2 is an order of magnitude or more less.

I think it is a no contest comparison. The reactor will kill the bell diffuser in efficiency.

I have the end all statement :-D


Bell diffusers take up space in your tank while inline reactors don't


End of story *LOL*
