Ideally, we want the water to flow that way (red lines) but trust me, it does not .
I put some coloring in the water to observe the water flow in one of my experiments.

Yeah thats and ideal sketch
Did you redirect your inlet flow?
How did you callor the water? what solution did you use?
If you want the water to flow like that, you need to stick an elbow (or curved fin) below the atomiser (in your design). If you use an elbow, you'll need to make sure its well sealed on the outside.
Actually, now your design makes more sense than before. Not a bad idea, but I think the bio-balls will stuck at the top due to the irregular surfaces.

Why use punctuation? See what a difference it makes:A woman, without her man, is nothing.

yes, that is the idea, but instead of elbow, I just used piece of thick platic glue it to the inlet of canister head 45 degree (inner side).
Not sure about bio ball, have not try that, may not even be necessary.
If you atomise the CO2, and the flow rate is high, you won't need bio balls. I never had to when I was running about 2000L/h on the NA version. I had to bubble pretty fast to satisfy the needs of a 6'x2'x2' tank. Not even atomised.

The picture is upside down. If you use it that way, the co2 will flow out in bubble form.
If you've learnt, teach, if you have, give.
Don't walk behind me as I might not lead, don't walk in front of me as I might not follow. Walk beside me, as my friend.
Mohamad Rohaizal is my name. If it's too hard, use BFG. I don't mind.
Ribena? I don't think that good for fish . Maybe just boost up CO2 and see where the bubble move.

DIY CO2 in action:
YouTube - DIY CO2 reactor in action
NA method is to :
a) flip the filter up-side-down
b) the original water-in becomes water-out
c) the original water-out becomes water-in and a hose is connected to the centre of the blue-cap (where you put the PVC) and the end of the hose with elbow.
d) drill a hole at the cap (your case you use the red button) for co2
usage :
a) water will gush into via the hose and the elbow will create swivel effect
b) CO2 rise up and mix with the swivel water . Unresolve CO2 remains on top.
c) mixed water will move out from bottom
I have this NA reactor, if the water too strong, a lot of bubble will be gush out. I preferred the long PVC pipe reactor stuff with bioballs rather than this reactor, as the later one mix is almost 100%.
My design is a bit different than NA design.
a) Filter is up right
b) Use original in and out
c) The red button thingy located at inlet, one of the reason can switch the in and out (unless drill new hole).
d) Atomizer will help the dissolving rate
e) Redirect the input with piece of plastic (black thingy in the picture) to create swivel
f) Un-dissolved CO2 will be gathering in the inlet, thus there no way the un-dissolve CO2 gush out. Not sure if the water flow > 1200L/h though
bringing up an old thread. how's the co2 reactor Shadow? any leaks? i'm considering DIYing 2 using your design
No leaks. No drilling nor cutting any part of the filter, so it shouldn't leaks unless the filter is faulty. The only possible point for leakage is the CO2 entry if it is not glue poperly. Expoxy is prety strong glue, so should be ok.
cool thanks Robert. I'll make 2 for my use then do you always have to use the basin below the reactor as shown in your video?
nope, I put inside the basin only during experiment.
I am now using a resun FR to act as a external CO2 reactor. The only modification you need to do is to drill a hole for injecting the CO2. This resun FR can be bought at 10 to 20 dollars for a second hand one.
