Bk you mean right below the intake
 
Diffuser made out of PVC or gravel vac hooked up to canister filter. efficient plus less stuff in the tank......best there is.
 
im concerned, if you have a glass diffuser and you set it up next to the intake of your canister, then the co2 is going to go through your entire filter, isnt there a chance that some co2 will be lost somewhere in the filter?

Cannister Filter = closed system

What goes in comes out



If you are concerned about build up, no worries. I've been running co2 directly into the intake of my cannister filter for a year. Very occasionally I get a slight build up of co2, but it eventually(after a few minutes) gets big enough to become "unstuck" and pass on through. This happens *maybe* once a day and isn't noticeable unless you are standing next to the tank. Additionally, it's not a large amount of co2, and it doesn't harm the filter.

i think you just described a fart.
 
I wouldn't run my CO2 through my canisters anyway. I'm pretty serious about my CO2 so I am adding quite a bit. A nice big bubble could easily build up in the canister and stop the flow and burn out your motor. It also makes noise when you have air in the filter. A DIY set up or a very low bubble count would probably be safe, but I would get an airlock going and burn out the motor on day one. Filters are expensive, I don't want to break it making it do something it wasn't supposeed to.

I don't like diffusers because you still loose a great deal of CO2, its a passive system, and they're delicate and the ceramic gets gunked up and need cleaning, not often, but my inline reactors have been running for 3+ years and I haven't needed to do one iota of maintenance.

I use inline reactors. Some of my more serious counterparts have started using inline pumps with a needle wheel impeller for great results. I want something that will dissolve the CO2 completely and then distribute that CO2 saturated water all over the tank.
