The reactor technology of the new millenium :). It can dissolve 1000-1200 bubbles per minute. The CO2 gas is dissolved 100%. There is absulutely no CO2 leak. It's dimensions are 8x2 inc(20cmx 5cm). This samole works 450 Lt/h water circulation. It may be used within tanks up to 250 gallons. It can be adapdet tobigger tanks by using bigger and stronger pumps. Cost is 5$, power head excluded.

Strong powerhead forcing water through it. The direction of the water flow (against the side of the tube; see last picture) rather than having it go straight down causes a vortex effect.

1000-1200 bubbles per minute? That's a lot. Assuming 10 bubbles = 1mL, You're gonna get 100 mL to 120 mL of dissolution per minute? Hrmm.

It looks like the external one has the water entering the side, along the side of the bottle (?), generating a vortex, and exiting from the center of the bottle at the bottom. And, the CO2 enters at the top in the center. So, the vortex keeps the CO2 captured in the middle, where it stays long enough to dissolve in the water around it. And, the "bottle" looks like two bottles with the bottoms cut off, and joined to make a double ended bottle with a neck at each end. Am I right? It looks like it would work very well, but I have no idea how much CO2 would dissolve, nor how much this would decrease the flow from a powerhead or pump.

The internal version looks like it works the same way, and since the photo shows it in action, you can see what a powerful vortex it generates. If it were to not dissolve any of the CO2 you would see it bubbling out the bottom.

I like it... I like it alot!

great idea.

If only I had some seethrough acrylics!

According to my calculations it dissolves the 100-150 ml. gas, that I have put inside the tube, within 1 minute.
The "bottle/clear pipe" is a cheap bottom cleaning pipe that is made in Turkey. It looks as if it was made specially for my vortex reactor. You may use acrylic pipes or anything similar to this one.

Hoppy,
it works exactly like you've described. All CO2 is dissoved, no CO2 escapes from this reactor.

Just pay attention to the size of the bottom exit hole. Its size and the rector's length is very important and should be proportionate. If you make the hole bigger than it should be, then no vortex occurs. If you make it smaller than it should be, then the vortex is slim and results in CO2 escape.
You have to work a little and try different sizes until you reach the optimum hole size. I was lucky to find it at first try, but I tried other sizes to make sure it's the optimum one.

I would think you could fine your required materials in the python gravel cleaners. one end for co2 injection, and the other for water exit then you drill and plumb in the exit hole.

well.. I would say to sue the python grave,l cleaners for a few reasons.

you can fine the piping as long as you want it to be.
the end caps can be bought easily and easily connect and can be easily sealed to the tubbing.
the python gravel cleaners have a narrower diameter and would make the vortex spin even faster with more force.

but what do you do at night when you don't need co2 injection? you can't turn off your filter.
I use a PH controller with a selenoid.

The material I used is also a gravel cleaner. You may use anything with similar shape and that is hard plastic (cola bottles won't work, needs something harder).
