DIY Co2 w/ Canister Filter

[Dudun]

Just purchased a Eheim 2232 for my 20gal tall.

How would I go about injecting DIY CO2? I don't have a diffuser, so is there a way to take it into the canister?

Any ideas will be greatly appreciated.

Place CO2 output just under Eheim intake - even better if a coarse sponge prefilter is involved...

Try a CO2 reactor. http://www.rexgrigg.com/diy-reactor.htm

If u feed the co2 directly into the intake, the cavatation resulting from breaking the co2 bubbles may hurt ur filter in the long run.

I put the CO2 line directly into the intake, I use 2236's as CO2 reactors and they've been running like the day I bought them, they only make a little noise when they burp excess CO2 occasionally.

I diffuse through my canister as well (XP1) and it's the easiest and most efficient way. No need to purchase anything else. I've never heard of anyone running into filter problems using this method. I would suspect something other than Co2 was the problem...
