I'm curious to see which method everyone is using these days to inject Carbon Dioxide (CO2), pressurized and DIY. Are you using a CO2 Glass Diffuser to mist/dissolve bubbles within the flow of the planted tank, or are you using a inline reactor? Any particular reason why?
inline diffusor to keep tech stuff outside the tank and because of better co2 spread. in my nano I have normal diffusor because of budget
generaly i use glass diffuser for tank less of 80l and so for the volume more importante i use reactor. david
Like what David said, I find it better to use glass diffusers for tanks that are relatively small in size like a 75g or less and anything bigger, it would be better to use an inline reactor.
I like glass diffusers for tanks 75G and below. Larger tanks I find needle wheel pumps are the best. Followed by this.
Orlando, can you please tell us which pump you have used for that and fi you have drilled the wholes into the rotors yourself?!
I use Danner Needle Wheel pumps, these come with everything ready to go. The only thing I add is a little plumbing. The pumps come in many sizes, so I use the appropriate size for the tank specs. This pump is the 9.5 Needle wheel pump by Danner.

I have used several types of diffusers and reactors as well. The good looking glass diffusers however do use an relatively high pressure to bring the many tiny bubbles in the cube but, after short time algae will come at this expensive Japanese diffusers surface and do give an certain inconvenience.. I have made an unbeatable perfect working CO2 reactor with use of two clear filter housings. use in line at the outlet of the filter. This do give an real 100% solve of the CO2 in the water. Plants react fantastic and do have an serious less use of CO2 also. interested?? Go to my album in my profile Peter
i agree about the glass diffuser issue, the thing is keep it clean !!! What i do in a small tank ( 50g ) is to inject the CO2 into the inlet of the canister, so that bubbles would move against the flow and diffuse then spread by the output of the canister.
@EFM: IMO, put co2 output to canister inlet is not good idea, because some bacteria in filter media need oxygen to live. inject co2 to filter will kill them. i'm using this diffuser for my 11gal tank.. it produces very tiny co2 bubble, just like reactor has don't know exactly name of this diffuser, it looks like an air stone huh? but in white color :-" very effective for 15gal tank and smaller
Yup... Beside that, canister filter work in vacuum condition. Some people had bad eexperienced when they put the CO2 to canister inlet. It made the canister broken.
It can cause airlock, basically too much air inside the canister causing the impeller unable to push the water out.
this is my friend's ceramic atomizer diffuser, he bought this at Dave Chow's showroom with 14 bucks and this one is DYMAX ceramic atomizer diffuser http://www.mydymax.com/index.php?pa...ufacturer_id=0&option=com_virtuemart&Itemid=1
The one from Dave Chow need higher pressure than usual but the bubble is very-very fine like a smoke.
anyone ever tried this inline diffuser? works very good in my 45L tank... diffuse like smoke.. [ame="http://www.youtube.com/watch?v=7IxD2Ob3e4g"]UP Atomizer Inline Diffuser[/ame]
