CO2 inline diffuser through cannister intake?

Thinking of getting a co2 inline diffuser. I know it is meant to go in the outtake, but would it be a good idea to connect it to the intake of a 2217 and use it as a CO2 reactor?

It is better to place it on the output side rather than the intake side. This is because you don't want junk/waste/detritus accumulating inside the reactor.

I purchased a “Boyu” diffuser on EBAY.
I installed it in the intake hose of my XP2 canister (outside the tank).
It works extremely well and does not emit micro bubbles into the tank (7up effect)
It only cost about $9 shipped from Hong Kong and took 10 days to arrive.
I’m going to buy more of them.

I just bought one of those and put it on the output of my 2217. I like it. Works great at diffusing without killing the flow like reactors do. I get some tiny bubbles, probably due to my high bubble count, but I don't mind them at all.

I've been using an airline tee to inject CO2 on the input side of a fluval 404 for the past couple of weeks and so far it's working well. I do get a small amount of CO2 mist later in the day but nothing bothersome to me. I started out using an AquaMedic reducing tee that I had laying around but then DIY'ed one that I'm using now. Cost of the DIY was around $5.

Should I be concerned about killing BB, and messing up my in line diffuser from the crap that enters through the intake?

Well, the main issue with placing the diffuser on the intake side is that it will accumulate dirt and other detritus, meaning you have to clean it more often.

I am not sure what you mean by "killing BB", however.

BB = Beneficial Bacteria maybe?

I retract my statement about this inline diffuser. Saw my dc was blue and found out it was leaking by the seams of the clear window. Oh wells, at least it was only $9.

I've run my reactor on both the intake and output, and both worked ok. If your reactor has media in it, then I'd put it on the output so it doesn't get gunked up. I actually just run mine right into my canister intake nowadays. As far as killing the bacteria, I don't seem to have issues in my tank, but realistically I have no way of knowing how much or what sort of bacteria is growing in my canister. The muck that accumulates in the filter looks just like every other bacterial slime I've seen.

You could probably tell if your killing bacteria if you get ammonia/nitrite readings? Considering so many people do it, it is probably not a concern...
