Now I like making things but have been nomadic over the past 5 years and so do not have as many tools as I'd like.

Thought of making a Cerges style reactor but then thought of settling for a commercially available inline diffuser.

Then I saw this thing by Jaqno called a prefilter and something clicked in my head.

Right now, with the water coming from the top, it can only handle a low rate of 1bps before the CO2 builds up and the bubble gets into the path of the incoming water but I suppose with a L shaped elbow, I should be able to get the water to swirl and have the reactor able to handle a much higher injection rate.



Come to think of it, there's a simpler solution. No swirling needed. The prefilter comes with two media separators. All I need to do is to stack them inside and place a fine mesh to prevent any CO2 bubbles from being sucked into the outflow at the bottom.

Now I'm a bit of a jack of all trades, master of none kind of guy so please correct my physics anytime but the way I look at it, even with no swirling to increase contact time, if the bubbles are caught by a mesh, there's no way that a 3 - 4bps rate can generate enough buildup to force the water level from the 2000l/h flow completely out from the chamber.

Found some unused parts from other filters lying around and siliconed them inside to give me some turbulence to aid gas dissolution.



Not worried about any bubbles finding its way to the output at the bottom because I'll be placing some filter media or a bag of carbon inside.

Ive done a version of this with great success. 100% disolved co2 when I was using pressurized stuff. However, I put an inline atomizer on the pre-filters inlet and let the inherent foam and my Eheim classic 2217 do the disolving.

Jaqno actually makes a co2 reactor. I made a video of it years ago.
