Inline Diffuser?

[Michaelbknudsen]

What is a good way to run an inline diffuser with a DIY CO2 setup?

I am running two canister filters, and am currently diffusing through an elite mini.

I've seen some DIY diffusers made with PVC, basically two short PVC sections connected to a T joint, with an attachment for the CO2 hose on the bottom of the T and connections on either end to hook up the tubing for your canister filter like you would any other inline attachment. I would just search around for the instructions. If you're looking for something already made, I know GLA sells one in a few different tubing sizes as well.

I followed these instructions pretty close. I didn't use clear PVC as it is not cheap, but it was a real easy build and great alternative to a ceramic or glass diffuser.

There are two main designs for inline CO2 diffusers: the Rex Grigg reactor and the Cerges reactor. Plugging either in to google will give you several walkthroughs and testimonials from people that have used them. I've used both in the past, and they work fine.
