The CO2 reactor wheel venturi

In my weird on going obsession with CO2 diffusion and measurement, I've decided to try some new methods for both measuring CO2 as well as flow through reactors.

It uses an in line needle wheel pump that dices up the CO2 along with a typical 2" PVC Reactor tube.

The needle wheel grinds up any collection in the top of the reactor tube.
This maintains the pressure inside the reactor tube and creates a mist.
Somewhat like a recirculating skimmer does.

I'll post some pics later.

Does this mean combining two ideas? Making a reactor that contains the dual venturi, with needlewheel rotor pump inside the tube? Pictures and sketches should be fascinating!

Since I have no idea what a recirculating skimmer is, I haven't the slightest idea how this will work or look.

So you could basically have a totally separate system for CO2 with in/out flow in the tank? Or would you have it connected in line with your filters? Sounds like this would be crazy efficient!

I'm going to build a recirculating needle wheel CO2 reactor, similar to as you described (The needle wheel output connected to the intake of 2" PVC then ouput of PVC pipe to intake of needle wheel. Extra holes would be drilled into the loop to add sump water and extract CO2 rich water.


But two questions:


Including the CO2, should I also inject room air into the loop to obtain O2 rich water as well?


If the CO2 enriched output water was then feed directly to a submerged filter tower (i.e. poret foam) with this adversely effect the bacteria?


If CO2 and O2 enriched out water was feed directly to a submerged filter tower (i.e. poret foam) with this adversely effect the bacteria?


Thanks
