Hey guys, does anyone know where I can get a very small C02 diffusor? I bought the bubbler below from 88 in Sunway Damansara because it was only RM1 but the bubbles are way too big.

The others I saw were small but the tube to feed the C02 line was facing UP. I need it to be facing down.

Basically what I'm trying to do is fit a diffusor into a C02 reactor to increase the efficiency of the reactor. Any ideas on where I can find an appropriate one?

Hmmm.....injecting fine co2 bubbles into a co2 reactor, to increase the reactor efficiency? Sounds doable..........

But second thought, the fine co2 bubbles from the diffusor will still be trapped at the top of the reactor (if the air does not dissolve into the water fast enough).

Thirdly, can you share with us how to insert a tube/diffusor into a co2 reactor. Thanks, bro.

the wood ones are good at prodicing fine bubbles. i'm using one for my TB venturi.

Currently the bubble is coming straight out of the airline tubing. I suspect that by using the diffusor, it'll greatly help diffusion.

I'm using the Dymax C02 reactor available from most LFS. It's made from green plastic. In any case, I'll take pics and show you.

Never thought of the wood ones before. Thanks! Will try that and see. What's a TB venturi?

Any pictures of the reactor? How is the performance? I have yet to build mine...

it's not really a venturi as the hole is so big. no pix of it but it's ok now... not perfect but...working.

last time i use the airstone as the diffuser and now the handmade glass ceramic one.....like the ADA product but its an imitation...seems to be working good

Guys, this is another reactor. i suppose nathan is trying something like this too:

http://www.qsl.net/w2wdx/aquaria/diyco2.html (page size is a bit big)

but i wonder where does the excessive air escapes? through the eheim sponge below? still cant make out where it goes since no hole unlike TB venturi's.

The reactor I have is this one - without the separating discs but with bioballs. Easily available at most LFS.

Instead of putting the unit inside the aquarium, I am running it inline with my canister, placing it outside the tank. I only have a 2.5ft tank so equipment in the tank is a big deal with me.


Where'd you get this?

I'm actually looking for something very similar to this:
Of course not exactly this lah cos I can't afford it. See that the C02 intake is at the bottom? Now, I want to place this diffusor inside the reactor.

Basically, here's what I'm trying to do:


Right now, I'm having the almost exact thing, except without that diffusor.
